Repair Rotted Window Sill & Estimating Repair Costs

by Tina Gleisner, in Wood Rot Repairs

everyone should enjoy their windows & not have to worry about needing to repair rotted window sill

Estimating home repair costs is challenging when you can't see the extent of the problem. At my handyman business, repair rotted window sill is a top handyman project. What might look simple when you start, can get complicated when you remove the rotted wood and find any hidden damage. The sad part is most wood rot could be prevented if home owners understood that routine (yearly) maintenance is critical to protecting their home.

When it rains, people cover up to stay dry. We know a brown bag disintegrates when it gets wet. When your home gets wet because of cracked paint or gaps which allow water to get into the wood, similar damage begins and can go unseen for years when hidden beneath the surface. By doing an annual inspection up close, you'll find these problems early and avoid the need to repair rotted window sill.

This article illustrate the various degrees of wood rot damage found by handyman technicians working for my handyman business. Starting with “routine maintenance” to prevent these problems, more complicated repairs increase in cost to where the window has to be replaced along with the framework holding the window in place.

Repair Rotted Window Sill: Paint Cracked or Peeling

Home owners knoestimating repair costs is challenging, especially when you can't see all the damage which is common when you go to repair rotted window sillw they have to paint their homes periodically. What many don't realize is certain parts of a home's exterior need more frequent maintenance. Any wood trim that sticks out further than siding, has flat surfaces like window sills or is close to the ground where splash back occurs, are more vulnerable to wood rot. These areas should be inspected every year and repaired (scraped and painted) as soon as damage or potential exposure to water like cracked paint, is observed.

Moisture that rots wood travels and causes more damage when not repaired, so make sure to repair rotted window sill (other wood rot too) quickly

Pockets of Punky (Soft) Wood Mean It's Time to Repair Rotted Window Sill

When water makes contact with wood, it creates an environment where fungi and mold are able to grow because the wood provides a source of food. As long as the moisture remains, the breakdown of wood continues and it is mostly invisible, hiding behind paint or going deep into the wood.

Let's look at how repairs and related costs to repair a rotted window sill change as wood rot is left to continue over time:

  • Small cracks or chipping paint on the window sill can be handled easily by scraping all loose paint and applying a high quality exterior paint … in under 30 minutes assuming you have the tools and materials (you want to include getting materials out and cleaning up).
  • One or two small (golf ball size or smaller) pockets of rot can be cleaned out to remove all damp wood, and filled with a product like Bondo (normally used for repairing cars, forms a nice hard surface) which is easy to sand and paint … in under 60 minutes if you have the materials.
  • When wood rot damage is more extensive (photo above right), you need to remove and replace one or more pieces of exterior boards. While technically, you should remove the window to replace the sill (3 to 4 hrs), most handymen will replace the sill in place … typically 1.5 to 2 hours, plus shopping.

Repair Rotted Window Sill: Rot Moving Up Vertical Trim Boards

While most wood rot starts at the window sill, the length of time the damage is ignored will affect the amount of damage that needs to be repaired. Where the damage in the photo above is large, it fortunately has not extended to either side of the vertical trim board. It also doesn't appear to have affected the window sill. The repairs are likely to include replacing the vertical board, and hopefully just cleaning out any punky wood on the sill underneath in 30 to 60 minutes plus shopping.

This type of repair is common when replacing the window sill, so together the repairs would take 2 to 3 hours plus shopping time as there are no standards for thickness of the window trim. When we replace window sills and other wood trim that is most prone to wood rot, we recommend using a composites like Azek which has no wood content. The material costs more but eliminates the worry associated with not doing the required annual maintenance to avoid a repeat of the problem in 5 to 10 years.

to repair rotted window sill often means replacing one or more boards, adding to repair costsRot on Window Jambs Surrounding Window

The photo at the left shows more extensive wood rot, and in fact required a new window as the damage extended into the jambs, the wood support pieces holding the window. While technically you can rebuild the window, the labor costs exceed the cost of a replacement window. Only with very old homes where the owner wants to preserve the authenticity of the architecture, do we rebuild windows.

When you look at a window you see the front of the window, the glass and the trim surrounding the window. These trim pieces are decorative, but more important they cover the gaps between the window and the siding to form a continuous weather barrier meant to keep water out. When moisture extends past the trim (window sill and/or vertical trim) boards, the wood rot starts to compromise the wood structure that holds the window.

Repair Rotted Window Sill & Rough Framing Around Window

They say a picture is worth a thousand words and that is certainly true for this story. A customer with Masonite siding ignored black spots all over her siding which told us the problem had been there for 20/more years. The photos tell the story of this window repair where the entire rough opening inside which the replacement window would sit, had to be rebuilt. Each of these repairs is unique so providing typical estimate repair times is not practical … you simply don't ever want to get into this situation!

rotted siding, window trim, window & missing structural framing are common jobs for a handyman business with the top project being to repair rotted window sill

The sad part of this story. Even with these photos, the customer continued to deny they had extensive wood rot and structural problems. We boarded up the window and siding below the window so we could review the damage the next morning, and together with the customer, determine the best strategy addressing technical requirements and budget. She declared there were no carpenter ants and it was a simple siding repair job that could be done by a local handyman.

    Thank you for all the information about how to repair rotted windows. I didn’t know that if there was extensive damage to the jambs that could mean you need to get a new window. I will have to see how much damage my windows have and see if I need to get new windows.

    Enjoyed your timely article very much. Would like to know what type of experienced vendor should I try to find to fix the water damage on window sill and casing. I think that’s what it’s called. When I moved in the inspector pointed out that a ‘flashing’ was put in upside down which was allowing rain water to seep in, and recommended getting it fixed. I hired handyman and showed him the report and he said he ‘caulked’ the areas over all the windows on that side of the house. Sadly this did not fix the problem for long, as I am now seeing the paint and plaster cracking on the sill and up along side the sill. It’s been raining heavily and appears to pound on west side of house. Thanks for any suggestions.

      Cookie, You’ve really got 2 problems, so let me summarize them here with recommended actions (and might be able to write more details in a future article).

      Your situation illustrates a common homeowner problem & hot button for me. Homeowners should ALWAYS find & fix the source of a problem before repairing the symptoms that resulted from the problem. From your description here, it sounds like:

      • Source of the problem – windows not installed correctly, with proper use of flashing to channel rain water away from the house
      • Symptom(s) of the problem – visible wood rot? paint cracking on window sills/framing … and it’s likely you’ve got hidden water damage inside the walls around/under these windows.
      • Solution to correct the “source” of the problem – is you’ve got to remove the problem windows & reinstall them with the proper flashing. When you do this, you hopefully will only need to repair (or replace) the window sill and some/all of the wood framing at the bottom of the window but as my article points out, if the damage is extensive, you may need to buy new windows. Inside the walls, there may be structural damage and/or compressed insulation from getting wet and these types of problems also need to be addressed.

      Removing & reinstalling each window will take 3 to 4 hours, plus materials … plus other repairs. Most homeowners are shocked at this cost which is why many handymen will try a “quick & dirty” solution like the caulking. It might work for a year but when there’s wood rot or severe weather, it won’t work for very long.

      Some other ideas for you to consider & you might not realize it but typically, one side of the house experiences much more wear & tear than the other 3 sides. This is challenging when it comes to painting your home because that one side needs to be painted more frequently.

      • Consider replacing the window sills on the problem side of your house with a composite material that will hold up to severe weather better. With my handyman business we used Azek but today there are less expensive alternatives, readily available at the box stores.
      • If weather & damage on that one side of the house is significant, consider replacing windows with … either aluminum (wood interior) windows and/or vinyl windows to eliminate as much wood material as possible.
      • Keep your windows but make sure you schedule inspection, repairs, painting & caulking annually to prevent the problems from reoccurring.

      Who can do this work? I wouldn’t go with a window company as they rarely have the skills (they generally contract this work out) or time built into their pricing to make the necessary repairs. Remodelers won’t be interested in this small a job … so yes, you do need a handyman. You need to interview several of them & ask them to explain step-by-step how they’re going to address your problems and it should become clear who knows what to do, and by their attention to detail in your discussion … who will do the best job.

      PS Make sure when the work is done, you’re there to watch things, learn (but don’t pester them too much) and make decisions on the spot when hidden damage is found.

          Thank you for being so detailed as to what is needed and who to call. I checked the link you sent. Too bad he lives in MA and I live in Central Coast California. Your explanation of the issue and process is greatly appreciated as I had no idea where this ‘flashing’ was supposed to be located, and seeing that link from the fellow in MA spelled it out for me. That the flashing on my window was installed upside down is insane. My windows appear to be metal or vinyl. Could not read the brand, but it looked like a large W with some print through the middle. Another label said AAMC Certification. My apologies for going on and on, I just can’t believe how much I learned from you and how grateful I am to know who to contact and what needs to be done to correct the problem. A huge thank you.

          Labor is generally based on the number of hours worked. My estimate for replacing rotted window sills is 3-4 hrs/sill, so if they took 10-12 hrs for actual repairs plus travel/shopping time for materials, I’d say this was probably a fair price.

    I’ll give you one more yuck factor for rotting sills: besides mold and fungi, bugs too, love the wet nest they make there. One of the windows we replaced had maggots growing in (charming eh?) and it was one the squishy to the touch spots you mention.

      I sold my handyman business in 2011 because I enjoyed the blogging, teaching, marketing, etc much, much more. Guess I love learning too much and once you’ve got all your business processes in place, it’s not as exciting.

      Window companies will always try to sell you replacement windows for the entire house. I like to tell people that it’s better to get good windows, even if you stretch it over 2 or 3 years. Start with windows in the rooms where you spend the most time – the kitchen, family room, etc. Replace these windows first so you’ll get the benefit of more airtight windows.

Other painting companies will tell you to find someone to do this first, before they paint because they don’t have those skills. What’s important is fixing the problems first, because painting over them will cause the paint to fail within 1-2 yrs.

    What a great post. Anyone with, well, windows would have this problem! I’m on the east coast and the humidity is nuts around those window sills. Thanks.

      On the east coast almost everyone has these problems because of wooden window sills. In Arizona, the windows are aluminum & there aren’t any sills, with the windows sitting inside stucco openings.

    Our windows all need to be redone. Maybe something that can be done over the summer.

    Our door frame needs some repair as the sun and dry heat takes it toll on it. Time to get to work

      Tara, Best not to delay. Doors have more problems at the bottom where rain water hitting the step below will bounce back up & hit the door or the wood just below it (called the kick plate). Make sure you also check that … and it’s best to paint/stain wood before it gets dried out … for future planning, e.g. put a reminder on your calendar every 2 or 3 years.

    So sad! When it comes to home repair, prior estimation is really important for you stay within your budget. If I can fix the damage myself, I do it carefully. But if this needs an expert help I also take chances.

      Alice, Good for you trying to handle repairs yourself. You can also save money by grouping small projects for 1 or 2 visits from your local handyman each year, and buying the materials ahead of time reduces their billable hours.

    Thank you for this. We just bought a house, so I’m still learning about repairs and all of that.

      Congrats Amber, Avoid getting overwhelmed by putting a list together & prioritize things. Safety items should be #1, then water damage which includes wood rot … and eventually you’ll develop a schedule for ongoing maintenance.

      You got it & scary how bad it gets when ignored for years. One homeowner I met with had holes from the outside of her home all the way indoors. They only discovered it when remodeling their basement to create a bedroom for their daughter … and sadly, didn’t have the money to make repairs.

    Where is the estimated cost for the repairs? Did I just overlook it on the page?

      Sara, Good question and I probably omitted the hourly rate as it varies depending on where you live. When I sold my NH handyman business in 2011, I was charging $84/hr for my technicians (MA was charging $92). When you hire an established company that does background checks, insurance and office staff, their costs are higher which I believe is justified because you’re getting a service which is guaranteed. At the same time I know you can find solo handymen on Craig’s list for $35/hr or more and they might be fine, and sometimes not. Shopping can take an hour, and basic wood, nails, etc aren’t terribly expensive but a new window installed will cost you at least $250.

      And it’s all relative as I had one bathroom remodel where we discovered the window inside the shower had to be replaced. The cost was about $1,000 because the window had been leaking (from outside) for years. We had to add some structural support joists to the wall & rebuild the rough opening for the window, replace all the insulation in that wall, put new drywall up (tape & mud), prime … you get the idea.

      The customer wasn’t happy so in the future, I’d write that type of invoice up as 2 jobs – the original bathroom remodel which came in on target, and make the window/exterior wall a separate invoice to try and avoid being blamed for exceeding my estimate.

      Mary, Having dealt with more than 30 homes that had this problem to a varying degree, it’s really not optional to repair rotted window sills as ultimately the siding will disintegrate as it did in the last house shown.

        What happens if the rot has spread to the siding as in the case that you’ve described in the post that I’m responding to?

          Martha, If the wood rot has spread to the siding, it’s almost certain that you’ve got serious problems. Here’s a list of things that probably need repair:

          • Remove window.
          • Remove rough opening which held window in place.
          • Remove siding & materials behind siding (all 4 sides) until you get to undamaged siding.
          • With any wall studs, if they’ve been eaten by wood rot, remove and/or sister another joist, to repair structural integrity.
          • Build new rough opening for replacement window.
          • Replace insulation, exterior sheathing & vapor barrier.
          • Install new siding (hint: you can borrow siding from less visible area for better color match).
          • Install new window & flash properly as that’s the most common reason for wood rot around a window.

    What is a good way to get better at estimates? I just started my own handyman/carpentry business and I keep shorting myself.

      Dave, You’re right that estimating is tricky & maybe I was able to get really good because we were doing about 35 jobs a week, with maybe 100+ projects in those jobs. So let me try to give you a few pointers.

      Never give a fixed estimate! For example, I would say it should take between 2 and 4 hours to install a storm door & explain that it often depends on how many pieces we find in the box because when the housing bust hit us, manufacturers saved cost by leaving the assembly to buyers. It can easily take 2 hours just to lay out 20–25 pieces on the lawn, and follow the directions to assemble a storm/screen door you buy at the box stores today.

      Then it can take another hour to properly install it. And when homeowners buy crap, I would have to do to their home, analyze the situation and show the customer where the manufacturer didn’t include an important piece … or because their door was unusual. Then I’d give them their options. These discussions are never fun because the homeowner just wants it done & they blame you for a problem caused by the manufacturer, builder or even their kid.

      For customers who insist on a fixed price, you can explain that you’ll have to add contingency, maybe 10-15% more time to cover surprises. You should also review the work once you get there, and list out potential problems that will cost more … right on their invoice, and get them to sign this before you start.

      Hope these tips are helpful.
