About our sand mastic in Sulhamstead
We renew sand mastic around sash windows and doors set in stone or brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. If you have mastic round period door frames that has failed and modern sealant on a period surround, we can help, whatever the surface.
Homes in small places like Sulhamstead often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Signs you need sand mastic in Sulhamstead
Timber frames move with the seasons. The movement cracks the mastic over time.
The problems people usually mention when they call are:
- Draughts and rain around sash boxes
- Gaps between timber frames and stone or brick
- Cement or filler used on old window joints that has cracked
- Tired mastic found when preparing windows for paint
Homes close to Church of St Peter include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before booking
- How long to leave it before use
- Who turns up on the day
- What happens if they find a problem under the old sealant
- Which sealant they’ll use, and why

Work for landlords, hotels and businesses

Landlords and agents in Sulhamstead can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for.
How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Avoid heavy scraping on the mastic joint
- Keep sills and gutters clear so water drains away
- Inspect the joints round the windows every year or so
- Ask the planning authority about consent for listed or conservation-area homes
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.
How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to a full day, depending on how many windows, and the area is left clean. In a small place like Sulhamstead, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- Keep pets and children clear of the area while we work
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height

Advice
What the job involves on each surface
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. We rake it out and renew it.
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair so it’s worth checking responsibilities.
Questions from Sulhamstead
Do you cover Sulhamstead for sand mastic?
Yes. We work across London and the South East, and Sulhamstead is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
Do you cover smaller places like Sulhamstead?
Yes. Sulhamstead is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can I choose the sealant colour?
Most of the time, yes. We’ll tell you which colours the right product comes in.
Should I use sand mastic or silicone?
That depends on your windows. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
What is sand mastic?
Sand mastic is a traditional material for pointing round windows and doors. It’s made with sand and a linseed-oil-based binder.

Why it’s worth doing now in Sulhamstead
An open joint round the frame lets weather in. Water can get to the frame and the masonry, so dealing with it now protects both. Where a wall is exposed, as many are in small places like Sulhamstead, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.
Why book with us
- Anti-fungal silicone where joints get wet
- Fully insured
- Approved under the ARBOMaster scheme
- We never seal over old sealant
