New build mastic for homes and businesses in Hook Green
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks. If you have messy sealant that spoils new finishes and shower seals failing in the first year or two, we can help, whatever the surface.
In a village or hamlet like Hook Green, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Questions from Hook Green
Is Hook Green within the area you cover?
Yes, Hook Green 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.
Is Hook Green in your area for new build mastic?
Yes. Our work covers London and the South East, and Hook Green is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear price.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Why does sealant fail so quickly in new builds?
New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.
Do you use white or clear sealant?
White and clear are the most common, but sealant comes in other colours too. We match the colour to the finish before we begin.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you when we finish.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Surface by surface
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. It’s resealed with an exterior sealant suited to the frame and wall.
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Each joint is cleaned and primed where needed so the sealant lasts.
How to look after the new joints
To keep the joints looking good and working properly:
- Don’t seal over failed sealant yourself
- Open a window or run the fan after bathing
- Get a leaking seal dealt with right away
- Look at the sealant regularly in the first couple of years
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Structural cracks in walls or ceilings
- A tray or bath that isn’t properly supported, until it’s fixed
- Cracked trays, tiles or worktops
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly.
Joints and surfaces we work on
- Windows & doors
- Kitchens
- Show homes
- Plot handovers
- Skirting & floors
- Bathrooms & en suites
What happens if it’s left?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. Around Hook Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.
