Window Mastic in Weston Underwood
Window mastic in Weston Underwood from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.

Window mastic in Weston Underwood
There are two joints on most windows. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. Common call-outs are for black, perished sealant on frames and a bead that doesn’t match the frame, across timber windows & doors, composite doors and aluminium frames.
Mastic can only go onto a dry, clean joint, so window work in Weston Underwood is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
You are covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or email us.

Why it’s worth doing now in Weston Underwood
The work is quick compared with the damage it prevents: it takes a few hours for a few frames, or a day or more for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. In a small place like Weston Underwood, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.

What else we do in Weston Underwood
Surface by surface
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
What we cannot put right
We will not take on work that will not last, so these are the limits:
- Broken hinges, locks or handles
- Rotten timber, which needs a joiner first
- Damp coming through the wall itself rather than the frame joint
If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.
Joints and surfaces we work on
- Composite doors
- Aluminium frames
- Timber windows & doors
- Window sills
- uPVC windows
- Patio & French doors
What we’re called out for in Weston Underwood
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.
These are the problems we are asked about most:
- Whistling draughts around closed windows
- Cracked sealant at the sill ends
- Black, perished sealant on frames
- Cracked or shrunken mastic around the frame
In the older streets around Church of St Lawrence, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Do you have insurance?
Yes, we are fully insured.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.

Access is agreed with you when the job is booked. For inside work, that normally means someone being in.

Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
What we do, step by step
All our tools and materials come with us in the van. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours for a few frames, or a day or more for a whole house. Somewhere as small as Weston Underwood, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
