What we do, step by step
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to a full day, depending on how many windows. Somewhere like Rake needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- On commercial sites, let us know about site rules
- Tell us about any water getting in

How we handle sand mastic in Rake
Silicone on a period window often looks wrong and doesn’t suit the building. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. We work on brick reveals, period & listed homes and sash and case windows, and common reasons people get in touch are patchy fillers round a sash window and draughty sash windows at the surround.
Homes in small places like Rake 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 as standard, so you’re not left on your own once the job is done.

Landlords, agents and businesses in Rake
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Letting agents often deal with us directly. Tell us the address, the job and how access works.
Sand mastic in Rake: local notes
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.
If you let a flat or house near Liss station, older sash windows in a rental need their mastic kept sound to keep the weather out. For site and facilities teams at buildings such as Rake CofE Primary School, its window and door frames need their mastic kept sound, just like a home’s. Homes close to Rake Mission Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Avoid heavy scraping on the mastic joint
- Ask us before painting near the mastic
- Inspect the joints round the windows every year or so
- Ask the planning authority about consent for listed or conservation-area homes
Leave the new mastic unpainted, which is the traditional advice. If you’re redecorating, ask us first.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
Your questions about sand mastic in Rake
Will you come out to Rake?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do sand mastic in Rake?
Yes. We work across London and the South East, and Rake is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or drop us an email.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Is sand mastic better than silicone for my windows?
We’ll talk it through with you. Period homes often look best with sand mastic and newer frames suit modern sealant.
Do you have insurance?
Yes. We’re fully insured.
Is there any odour?
Sometimes, a little. It fades as the sealant cures.
DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Why it’s worth doing now in Rake
New sash windows are a major, costly change, and in listed buildings it may need consent. Where the frames are in good order, new mastic seals the surround. Older cottages and farmhouses around Rake can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
