Window Mastic in Burnt Hill
Our applicators work in Burnt Hill on mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly.
- Cracked internal joints between frame and plaster
- Sealant in the wrong colour for the frame
- Gaps where the sill meets the wall
Surface by surface
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. The threshold and the bottom corners take the most water, so they get particular care.
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.
Window mastic in Burnt Hill
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. Where the air is getting in through the window itself, we will say so. If you are dealing with damp patches on the reveal after heavy rain and cold air getting in at the frame edge, we can put it right, whatever the surface.
Around Burnt Hill, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Your job is guaranteed for a year, as with all our work.

Signs you need window mastic in Burnt Hill
Sun, frost and rain wear sealant out. Sunlight dries the surface out, until it loses its stretch and starts to crack.
It’s worth asking for a quote if you see:
- Damp patches on the reveal after heavy rain
- Draughts coming in around windows and doors
- Rushed sealant from a window installation
- Draughty joints inside around the window
Letting a property close to Pangbourne station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Why deal with it now?
Running fresh sealant over the old joint is tempting, but it won’t grip old, dirty sealant. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. Older cottages and farmhouses around Burnt Hill can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first.

How the visit works
You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes anything from an hour or two to a full day, depending on how many frames there are for a typical job. In a small place like Burnt Hill, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any previous sealing or DIY attempts
- Move anything stored near the joints
Getting a quote
Getting a quote is simple: tell us what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand, and we will come back to you with a quote.

DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Frames and glazing around Burnt Hill
Historic houses like Basildon Park (about 3.5 miles north-east) are a reminder that the area around Burnt Hill has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Yattendon C.E. Primary School, larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Church of St Peter and St Paul, the joint between an old wall and a newer frame is generally the first place rain gets in.
