Sand mastic in Hog Hatch
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant, and we’ll talk through which suits your home. We work on tenement windows, sash and case windows and stone surrounds, and common reasons people get in touch are open joints round the window box and draughts and rain around sash boxes.
In smaller places like Hog Hatch, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. Each frame material needs the right sealant against the right wall.
You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

Frames and glazing around Hog Hatch
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Farnham Castle (about 0.9 miles south) nearby, there’s older building stock in the area around Hog Hatch as well as newer homes. 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.
For site and facilities teams at buildings such as Folly Hill Infant School, the mastic around its windows and doors needs looking after like any other building’s. Homes close to St Mark the Evangelist Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Leave the new mastic unpainted
- Do not run silicone over sand mastic
- Ask the planning authority about consent for listed or conservation-area homes
- Clear gutters so water doesn’t pour onto the windows
Do not run silicone over the new mastic. If anything cracks, get it looked at before trying a quick fix.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
What the job involves on each surface
Brick reveals
Gaps between frame and brick let in rain and draughts. Renewing the mastic closes it.
Period and listed homes
Period homes look their best with traditional materials, and sand mastic is one of them.
FAQs for Hog Hatch
Do you work for landlords with property near Farnham station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Is Hog Hatch within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can I choose the sealant colour?
Yes. Sealants come in white, clear, grey and other colours, and we will agree it with you first.
What’s sand mastic made of?
Sand plus a binder based on linseed oil. It’s applied by hand and finished to sit neatly against the masonry.
Are you fully insured?
Yes. We’re fully insured, and we have been doing sealant work for more than 20 years.
Can you do several jobs on one visit?
Yes, we can. More than one area can go on one quote.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can old silicone round a sash window be swapped for sand mastic?
Yes, we do this often. The old silicone has to come out completely so the mastic beds in well.
Do you need sand mastic in Hog Hatch?
Over the years, sand mastic weathers. It dries out, cracks and loses its grip on the stone or timber.
It’s worth asking for a quote if you see:
- Draughts and rain around sash boxes
- Mastic that needs renewing before redecorating
- Gaps between timber frames and stone or brick
- Modern sealant on a period surround
For landlords with property near Farnham station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
Comparing quotes

- What happens if they find a problem under the old sealant
- Which sealant they’ll use, and why
- How much experience the applicator has
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What happens on the day
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours per window, depending on the condition of the joints, and the area is left clean. For a job in Hog Hatch, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic isn’t too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
How to prepare
- Let us know about stairs, lifts or work at height
- For indoor joints, keep the area dry beforehand if you can
- Tell us if parking is tricky

Why it’s worth doing now in Hog Hatch
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry, so dealing with it now protects both. Homes in smaller places like Hog Hatch can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before work begins, so you know where you stand.

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
