About our sand mastic in Redlands
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. Renewing it closes the gap and tidies the surround. We are often asked to deal with draughty sash windows at the surround and crumbling sand mastic round a window, on tenement windows, stone surrounds and brick reveals.
Mastic can only go onto a dry, clean joint, so window work in Redlands is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Big or small, you get the same 12-month guarantee in Redlands and across Surrey.

Frames and glazing around Redlands
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Farnham Castle (about 2.3 miles south-east) are a reminder that the area around Redlands 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’s traditional sand mastic.
Schools such as Crondall Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Farnham station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

How we quote for sand mastic
Your quote is based on your job. We take into account:
- Any mould that needs treating
- Access and height
- The old material and how stubborn it is
- Any working-time requirements on site
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.
Helping us quote
What to tell us when you ask for a quote:
- Photos by email, if that is easy
- What’s wrong with the joints now
- The type of property
- Where the property is
Asking for a quote is easy: let us know what needs doing and where. A few photos by email make the job easier to understand, and we’ll take it from there.
When to call us in Redlands
Most of it is simply age. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
Look out for these signs:
- Weathered mastic on the most exposed windows
- Cement or filler used on old window joints that has cracked
- Wind and rain getting in round a sash window
- Gaps where the frame meets the masonry
For an older house near a landmark such as Church of All Saints, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What your quote should include
- Which colour the sealant will be
- How much experience the applicator has
- Is VAT in the price?
- What preparation is included
How the visit works
We keep the work tidy and contained to the joints we are treating, so you can get on with your day. Expect the work to take a few hours per window, depending on the condition of the joints. For a village or hamlet like Redlands, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
How to prepare
- For business premises, tell us about site rules or sign-in
- Let us know about parking restrictions

Landlords, agents and businesses in Redlands
Landlords and letting agents in Redlands can book us as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
If you manage several properties in or around Redlands, several properties can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Keep modern sealant off the mastic
- Ask a joiner to look at soft timber first
- Find out about consent before window work on a listed home
- Plan mastic work ahead of painting
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
Why deal with it now?
If you’re redecorating, renew the mastic first. Paint over cracked mastic will not stop the gaps, and the new mastic is traditionally left unpainted. Older cottages and farmhouses around Redlands can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not guesswork. That is why we ask about the job first.
