Frames and glazing around West End
With historic houses such as The Homewood (about 1 mile south-west) nearby, there’s older building stock in the area around West End as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of 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 St George's include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as Claremont Fan Court School, its window and door frames need their mastic kept sound, just like a home’s.

Sand mastic in West End
Traditional burnt sand mastic blends with stone and brick surrounds. It suits period and listed homes, where modern sealant can look out of place. Common call-outs are for mastic dropping out of the joint and cracked mastic round a front door frame, on tenement windows, sash and case windows and stone surrounds.
Homes in small places like West End 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.
Whatever the size of the job, you get the same one-year guarantee.

How the job changes by surface
Stone surrounds
The stone is treated with care when the old mastic comes out.
Period and listed homes
Many older homes were built with sand mastic round the windows. If your home is listed, ask your local planning authority about consent.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Don’t run silicone over sand mastic
- Ask the planning authority about consent for listed or conservation-area homes
- Keep sills and gutters clear so water drains away
- Check the mastic when you check the paintwork
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
What affects the quote in West End
Your quote is based on your job. We look at:
- The old material and how stubborn it is
- The product the joint needs
- Access and height
- When we can work, for business premises
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

Why act early in West End
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. Where a wall is exposed, as many are in small places like West End, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

What we are called out for in West End
Age is the main cause. Even well-laid mastic needs renewing in time and how long it lasts depends on the weather it faces.
Any of these means the joints need attention:
- Gaps round a timber door in stone or brick
- Silicone on a period window that looks wrong
- Gaps between timber frames and stone or brick
- Window mastic to renew ahead of painting
Rented homes near Hersham station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.
What your quote should include
- How long the guarantee is
- How the joint is cleaned and prepared
- How long to leave it before use
- Whether the sealant suits the joint
How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to a full day, depending on how many windows and we leave things clean and tidy. In a small place like West End, access is normally 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
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before
- Clear items away from the joints we are working on
