What affects the cost of sand mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- The size of the job
- How many rooms, windows or areas are involved
- Access and height
- When we can work, for business premises
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

How we handle sand mastic in Hamstead
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It suits period and listed homes, where modern sealant can look out of place. If you are dealing with draughty sash windows at the surround and old cement repairs round a window that have failed, we can help, on brick reveals, tenement windows and period & listed homes alike.
Homes in small places like Hamstead often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

How it works
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a few hours for a single window, longer for several, depending on how much there is to do. Somewhere like Hamstead needs a little journey planning: 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.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Before we arrive
- Let us know about earlier repairs to the joints
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children

Advice
Honest limits
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Decayed frames that need repair
- Masonry that needs repairing
- Decisions on consent for listed homes
If you are not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.
What we seal
- Sash and case windows
- Brick reveals
- Period & listed homes
- Timber door frames
- Tenement windows
- Stone surrounds
Why act early in Hamstead
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. In a small place like Hamstead, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.

Questions from Hamstead
I let a flat near Lymington Pier station. Can you help?
Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. You can phone 0345 464 0079 or email us with the details for a clear quote.
Will you come out to Hamstead?
Yes, Hamstead is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or drop us an email.
How long does sand mastic take to harden?
The surface skins quite quickly and it hardens fully over a longer time. The weather and joint depth both affect it.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
Can I choose the sealant colour?
Normally, yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before we start.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Different surfaces, different methods
Tenement and terrace windows
Where a building is shared, window work may involve neighbours, so check who is responsible first.
Brick reveals
An open joint at a brick reveal lets weather in. Renewing the mastic closes it.

Hamstead homes and the weather
Hamstead is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Historic houses like Swainston Manor (about 3.3 miles south-east) are a reminder that the area around Hamstead has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Swainston Manor, about 3.3 miles south-east, is one of the historic houses in the wider area around Hamstead.

Do you need sand mastic in Hamstead?
Rain on the window surround works into any crack and loosens it further. Exposed elevations usually fail first.
Look out for any of the following:
- Cement or filler used on old window joints that has cracked
- Weathered mastic on the most exposed windows
- Old sand mastic that has cracked, crumbled or fallen out
- Gaps between timber frames and stone or brick
Rented homes near Lymington Pier station change hands often, and any sash windows need sound mastic to keep draughts and rain out.
