Wooden Hill Window Mastic
Mastic around window and door frames, sills and patio doors for homes and businesses in Wooden Hill and across Bracknell Forest. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Untidy mastic left by window fitters
- Leaking joints at the ends of sills
- Draughty joints inside around the window
What the job involves on each surface
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. If we find rot, we will tell you before going ahead, as a joiner will need to deal with it.
Window mastic in Wooden Hill, done properly
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. Either or both can be done. Typical jobs include rushed sealant from a window installation and damp patches on the reveal after heavy rain, across aluminium frames, composite doors and timber windows & doors.
Around Wooden 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.
Every job is covered by a 12-month guarantee.

Why act early in Wooden Hill
Not every sealant suits a window. Interior caulk and bathroom silicone aren’t made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. In a small place like Wooden Hill, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us and we’ll give you an honest view and a quote.

How it works
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for a handful of frames, longer for a whole house. In a small place like Wooden Hill, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints

Windows and doors in Wooden Hill
Wooden Hill is part of Bracknell, one of the post-war new towns. Many homes date from the post-war decades, and many will have had their original windows replaced. The mastic around replacement frames ages too, and gaps at sills and frame heads are where water gets in. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Wooden Hill Primary and Nursery School? Then its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as St Michael and St Mary Magdalene's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What else we do in Wooden Hill
Do you need window mastic in Wooden Hill?
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
If you can see any of these, it’s time to have the joints looked at:
- Sealant in the wrong colour for the frame
- Cracked internal joints between frame and plaster
- Black, perished sealant on frames
- Rain getting in at the frame or under the sill
Letting a property close to Bracknell station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

Questions from Wooden Hill
Do older homes in Wooden Hill need their sealant replacing?
Generally, yes, if it’s cracked, shrunk, mouldy or coming away. New sealant will not stick to old, so the old bead has to come out completely first.
Will you come out to Wooden Hill?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Do you work for landlords and businesses?
Yes, regularly. We can quote for several properties at once, and between tenancies is a good time for the work.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Will resealing my frames help with draughts?
Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that’s a different fix, and we’ll say so.
