Sand Mastic in Penton Hook
Our applicators work in Penton Hook on traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly and a 12-month guarantee.
- Weathered mastic on the most exposed windows
- Crumbling sand mastic round a window
- Draughts and rain around sash boxes
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Ask a joiner to look at soft timber first
- Ask us before painting near the mastic
- Ask the planning authority about consent for listed or conservation-area homes
- Go gently near the mastic when preparing windows
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.
Sand mastic for homes and businesses in Penton Hook
Sand mastic skins over fairly quickly but full hardening takes longer. Traditional guidance is not to paint over it, so ask us before you decorate. If you’re dealing with silicone on a period window that looks wrong and crumbling sand mastic round a window, we can put it right, whatever the surface.
Outdoor sealant needs dry, clean surfaces, so work on frames around Penton Hook is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.

Signs you need sand mastic in Penton Hook
Sand mastic slowly weathers. It dries out, cracks and loses its grip from the frame or the masonry.
People usually contact us after spotting something like this:
- Patchy fillers round a sash window
- Mastic worn away on windows facing the weather
- Old sand mastic that has cracked, crumbled or fallen out
- Wind and rain getting in round a sash window
For site and facilities teams at buildings such as Laleham CofE VA Primary School, the mastic around its windows and doors needs looking after like any other building’s.

FAQs for Penton Hook
Do you cover smaller places like Penton Hook?
Yes, Penton Hook is covered. 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.
Can you do sand mastic in Penton Hook?
Yes. We work across London and the South East, and Penton Hook is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Can I choose the sealant colour?
We help you choose a colour that suits. The product needed can limit the range.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.

What sand mastic looks like in Penton Hook

With historic houses such as Botleys Mansion (about 2.8 miles south-west) nearby, there’s older building stock in the area around Penton Hook as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.

Surface by surface
Brick reveals
We rake out the old mastic and pack deep voids before pointing.
Timber door frames
Sand mastic is used round timber door frames too. We renew it the same way as on windows.
DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

If the job is outside, mention outbuildings, exposed walls and how to reach them.

Advice
What happens if it’s left?

What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and give you a clear price before work begins.

- Full insurance on every job
- Neat joints and a tidy finish
