Window mastic for homes and businesses in Bevendean
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We are fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. We’re often asked to deal with draughts coming in around windows and doors and cracked or shrunken mastic around the frame, on window sills, composite doors and patio & French doors.
In a smaller place like Bevendean, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That’s hard on the mastic around frames and sills.
A one-year guarantee comes with the work, just as it does everywhere we cover.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Bevendean questions
Do you cover smaller places like Bevendean?
Yes, Bevendean is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Moulsecoomb station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Do you guarantee window mastic?
Yes. All our work carries a 12-month guarantee, and we’re ARBOMaster approved applicators.
Can new window sealant be painted?
Not normally, if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
Where are you based?
We’re based in Crawley, and we work across South East England, London and Scotland.
Can you seal the gap between the frame and the plaster indoors?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area.
Can you reach windows above the ground floor?
Generally, yes. Access is planned before we start, so mention the height and anything in the way.
Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too in Bevendean and across Brighton and Hove. We can quote a run of properties together.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.

What affects the quote in Bevendean
The price is agreed before any work begins. It takes into account:
- Whether old sealant or filler has to be cut out
- The number and length of the joints
- The type of sealant required
- How many rooms, windows or areas are involved
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- A few pictures by email, if you can
- The problem you’ve noticed
- If someone has resealed it before
- The type of property
Getting a quote is simple: let us know the job and the location. Photos by email help us understand the job, and we will take it from there.
How the visit works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It usually takes a morning for a couple of windows and a door. Parking around Bevendean 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.
- 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.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Keep pets and children clear of the area while we work
- Let us know about stairs, lifts or work at height

When to call us in Bevendean
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. When that sealant fails, water gets into the wall or under the frame.
Common reasons people contact us include:
- Draughty joints inside around the window
- Hard, cracked sealant around windows
- Leaking joints at the ends of sills
- Water coming in at the bottom corners of a door
For landlords with property near Moulsecoomb station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Window mastic in Bevendean: local notes
Bevendean is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Historic houses like Royal Pavilion (about 2 miles south-west) are a reminder that the area around Bevendean has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you look after a building such as Bevendean Primary School, its window and door frames need their mastic kept sound, just like a home’s. Homes close to Holy Nativity Community Project include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Bevendean is about 1 mile north-east of Brighton, in Brighton and Hove. Wherever you are in the BN2 postcode area, we can carry out window mastic at your property. 30 places in Brighton and Hove are on our list, from the larger towns to small villages.

Different surfaces, different methods
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. It comes out, deep gaps get backing rod and the joint is resealed.
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain can’t run into the wall.
Why deal with it now?
The work is quick compared with the damage it prevents: it takes most of a day for a typical house, less for a few frames. Wait for damp to appear and there may be plaster and decorating to sort out too. In an older home around Bevendean, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we’ll go through it with you.
