About our sand mastic in Telscombe Cliffs
We work across Telscombe Cliffs renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. We work on tenement windows, timber door frames and stone surrounds, and people most often call us about silicone on a period window that looks wrong and mastic that needs renewing before redecorating.
Many houses in smaller places like Telscombe Cliffs have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Surface by surface
Sash and case windows
On a sash window, the mastic joint shows on the outside so we finish it carefully.
Brick reveals
Sand mastic is also used where timber frames meet brick. It gives a traditional finish.
Why it’s worth doing now in Telscombe Cliffs
Filling over old, loose mastic does not last. We remove the loose material first so the new work lasts. In a smaller place like Telscombe Cliffs, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
What you pay reflects the work, not guesswork. That is why we ask about the job first.
What you get with us
- Neat joints and a tidy finish
- Anti-fungal silicone where joints get wet
- 20+ years of sealant experience
- Every job guaranteed for a year

Quotes for sand mastic in Telscombe Cliffs
We don’t publish a price list. What we look at:
- The size of the job
- How many rooms, windows or areas are involved
- When we can work, for business premises
- Whether old sealant or filler has to be cut out

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
How the visit works
At the end, we look at the finished work together. The visit itself usually takes a few hours for a single window, longer for several, depending on the size of the job. In a smaller place like Telscombe Cliffs, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.

Questions from Telscombe Cliffs
I let a flat near Newhaven Town station. Can you help?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Does living near the coast affect sand mastic in Telscombe Cliffs?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Do you cover Telscombe Cliffs?
Yes. We cover Telscombe Cliffs and the rest of East Sussex, as part of our work across South East England, London and Scotland. For a quote, phone 0345 464 0079 or email us.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or send us an email.
When will the new mastic be hard?
A skin forms quite soon, but full hardening takes longer. We will explain what to expect before we leave.
Should I check with the council before work on a listed or conservation-area home?
Check with your local planning authority. They’ll tell you if consent is needed for work to your windows.
How long does sand mastic take?
As a guide, most jobs take a few hours for a single window, longer for several. Larger jobs naturally take longer, and we will say how long yours will take.
What we cannot put right
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Cracked or broken glass
- Planning or listed building consent (your local planning authority decides)
- Crumbling stone or brickwork round the window
If in doubt, call 0345 464 0079 or email us and we will say what we think.

Windows and doors in Telscombe Cliffs
Telscombe Cliffs is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Telscombe Cliffs Community Primary School, the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near Ascension Church, the joint between an old wall and a newer frame is generally the first place rain gets in. Rented homes near Newhaven Town station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.
