FAQs for Brick Hill
Do you cover Brick Hill for sand mastic?

Do you cover smaller places like Brick Hill?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
What’s sand mastic made of?
It’s the traditional filler for the joint round timber windows and doors. It’s made with sand and a linseed-oil-based binder.
How long does sand mastic take to go off?
It forms a skin fairly soon and it hardens fully over a longer time. Timing depends on the weather and the joint.
Can I choose the sealant colour?
Most of the time, yes. We’ll tell you which colours the right product comes in.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we are using and why.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Can sand mastic be painted?
It’s traditionally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
Sand mastic for homes and businesses in Brick Hill
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted and we’ll advise if you are redecorating. Typical jobs include weathered mastic on the most exposed windows and gaps between timber frames and stone or brick, across timber door frames, tenement windows and brick reveals.
Mastic can only go onto a dry, clean joint, so window work in Brick Hill is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Work for landlords, hotels and businesses
We also work for property managers and facilities teams. Several sites can be quoted together, and we are fully insured for the work.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Aftercare tips
So the new joints stay in good condition:
- Renew mastic before redecorating the windows
- Have rotten timber repaired before new mastic goes in
- Find out about consent before window work on a listed home
- Leave the new mastic unpainted
Leave the new mastic alone while it firms up. It forms a skin fairly soon but needs longer to fully harden.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall so early renewal protects both.
What the job involves on each surface
Timber door frames
A neat sand mastic joint round a front door suits a period home.
Brick reveals
We rake out the old mastic and pack deep voids before the new mastic goes in.
Windows and doors in Brick Hill
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. Historic houses like Botleys Mansion (about 4 miles east) are a reminder that the area around Brick Hill 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.
Rented homes near Sunningdale station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. If you live in an older home near Church of St Saviour, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Do you need sand mastic in Brick Hill?
Previous repairs in cement or silicone often trap water or crack away. They don’t move with the timber, and they generally need raking out.
Most people get in touch after spotting something like this:
- A silicone bead on a sash window that spoils the look
- Open joints round the window box
- Weathered mastic on the most exposed windows
- Cement or filler used on old window joints that has cracked
For site and facilities teams at buildings such as Valley End CofE Infant School, its window and door frames need their mastic kept sound, just like a home’s.

How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours per window, depending on the condition of the joints, and the area is left clean. Somewhere as small as Brick Hill, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Let us know if you’ve seen damp or leaks
- Tell us if parking is tricky

Advice
Why deal with it now?
Filling over old, loose mastic doesn’t last. Raking out and preparing the joint gives it a sound base so the new work lasts. Where a wall is exposed, as many are in small places like Brick Hill, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.

Can I do it myself?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
