Brighton Hill Window Mastic
Window and door frames in Brighton Hill need attention? We remove the old material, prepare the joints and seal them properly.
- Draughty joints inside around the window
- Mastic that’s falling out in pieces
- Gaps where the sill meets the wall
Window mastic in Brighton Hill, done properly
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. Typical jobs include leaking joints at the ends of sills and rushed sealant from a window installation, on uPVC windows, patio & French doors and composite doors.
In a smaller place like Brighton Hill, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That is hard on the mastic around frames and sills.
All of our work is guaranteed for twelve months.

Landlord and commercial work in Brighton Hill
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.
We also work for property managers and facilities teams. We can quote a run of properties together.
Why act early in Brighton Hill
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. In a smaller place like Brighton Hill, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.

Common problems we fix in Brighton Hill
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
Keep an eye out for any of the following:
- White mastic on grey or black frames
- Draughty joints inside around the window
- Rain getting in at the frame or under the sill
- Untidy mastic left by window fitters
In the older streets around The Church Of Christ The King, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Questions to ask before booking
- What happens if the job turns out different
- Which sealant they’ll use, and why
- The length of the guarantee
- Is the old sealant removed completely?
How it works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes most of a day for a typical house, less for a few frames. Parking around Brighton Hill is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.
Preparing for the visit
- Clear items away from the joints we are working on
- Tell us about any water getting in
- Tell us if parking is tricky
How to get a quote
Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand, and we will come back to you with a quote.
Advice
Different surfaces, different methods
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We will tell you if that’s what we find.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
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.
