Window mastic in Windsor and Maidenhead: how it works
Frames and walls don’t move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. We work on timber windows & doors, window sills and patio & French doors, and the jobs we see most are black, perished sealant on frames and cold air getting in at the frame edge.
You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for a handful of frames, longer for a whole house in most cases.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.

Windows and doors across Windsor and Maidenhead
In Windsor and Maidenhead, window mastic work takes in houses, flats, conservatories and commercial glazing, in Maidenhead, Windsor and Boyn Hill and well beyond. Every outside joint is sealed dry and clean, so the forecast plays its part.
From Victorian terraces to post-war new towns and modern estates, homes across the South East and London cover every era. Each needs the right sealant for its age and materials.
Maidenhead: If you live in an older home near All Saints' Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Rented homes near Maidenhead station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
What sealant work cannot fix
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Damp coming through the wall itself rather than the frame joint
- Rotten timber, which needs a joiner first
- Draughts through the window seals rather than the frame
For landlords and businesses
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
What affects the quote in Windsor and Maidenhead
Some jobs are bigger than they look, and some smaller. The main factors:
- The amount of work
- How easy the joints are to reach
- Any working-time requirements on site
- The old material and how stubborn it is
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

Leave it or put it right?
Choosing the product is half the job. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost.
What your quote should include
- How the colour is chosen
- Whether they’re fully insured
- What product goes in the joint
- Who turns up on the day
Signs you need window mastic
On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
Signs it’s time to call us include:
- A bead that does not match the frame
- Water coming in at the bottom corners of a door
- Old mastic that has gone black or come away
- Mastic that has split away from the wall
