Window mastic in Brewer Street, done properly
Over two decades of sealing frames has taught us which products suit which walls. We’re fully insured ARBOMaster approved applicators, and we give a 12-month guarantee on the work. We work on timber windows & doors, uPVC windows and composite doors, and common reasons people get in touch are mastic that’s falling out in pieces and whistling draughts around closed windows.
Somewhere as small as Brewer Street, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
Each job carries a 12-month guarantee, whatever its size.

What affects the quote in Brewer Street
We quote each job individually. These are the things that affect it:
- The old material and how stubborn it is
- How easy the joints are to reach
- The amount of work
- How many rooms, windows or areas are involved
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Whether it has been sealed before
- Photos by email, if that is easy
- Access, such as stairs, a lift or height
- The rough size of the job
For a quote, phone 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. You will have a clear quote before any work starts.
Window mastic in Brewer Street: local notes
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to Church of St Mary the Virgin include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Schools such as Bletchingley Village Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
Brewer Street is about 2 miles south of Caterham, in Surrey. Across the RH1 area, our applicators can take on window mastic. Our Surrey coverage runs to 395 places, and Brewer Street is one of them. There’s also a page for Crawley, about 11 miles away.
Our applicators cover all of the RH1 postcode area for window mastic and the streets around it. Window mastic is available to properties on Whitehill Lane and Brewer Street and the roads around them. We also cover Nutfield (1 mile south-west), Chaldon (2 miles north), South Merstham (2 miles west), Merstham (2 miles north-west) and South Nutfield (2 miles south-west). Within a short drive, we also cover Epsom (9 miles north-west), Horley (6 miles south-west), Redhill (3 miles west), Ewell (10 miles north-west), Reigate (4 miles west) and Dorking (10 miles west).
Around Brewer Street
In Brewer Street, that means homes and buildings near Merstham Park School, Oakhyrst Grange School and The Prince Albert Public House and the streets around them. The nearest railway station is Merstham station, roughly 2.2 miles west. A little further out are East Surrey Museum (2.2 miles north-east) and The Belfry (3.1 miles west). Not far away are Mercers Lake and Bay Pond.
DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep paint and stain on wooden frames in good order
- Use gentle cleaners on frames and sealant
- Walk round the house once a year and look at the joints
- Do not aim a pressure washer at the joints
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. Resealing closes it.
Why it’s worth doing now in Brewer Street
Choosing the product is half the job. Interior caulk and bathroom silicone aren’t made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Where a wall is exposed, as many are in small places like Brewer Street, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.

Common problems we fix in Brewer Street
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, and a gap filled solid can’t flex. Backing rod sets the right depth.
People normally contact us after spotting one of these:
- Whistling draughts around closed windows
- Untidy mastic left by window fitters
- Sealant in the wrong colour for the frame
- Water coming in at the bottom corners of a door
Letting a property close to Merstham station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
