Why act early in Borough Green
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. In an older home around Borough Green, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.
Why book with us
- Fully insured
- Old sealant always removed completely
- Colour picked to suit the job
- You choose the colour before work begins

About our new build mastic in Borough 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 new bead bonds properly rather than sitting on a layer of grit. If you are dealing with plot mastic for developers ahead of handover and sealant that never bonded to the surface, we can put it right, on windows & doors, show homes and kitchens alike.
For a new home in or near Borough Green, it’s worth checking the sealant early. Common snags include open skirting joints, lifting shower seals and gaps around frames.
You get a one-year guarantee, the same in Borough Green as everywhere else we work.

Do you cover Borough Green for new build mastic?
Yes. We work across London and the South East, and Borough Green is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.
Do you work for developers?
Yes. We work through plots to your schedule, room by room. Tell us the plots and the joints involved and we will quote.
Can you reseal over the builder’s sealant?
No. The old sealant is cut out fully, the joint cleaned and primed where needed, and a new bead applied.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you.
Why has my new-build shower seal failed already?
New homes dry out and move in their first couple of years, and sealant is often rushed onto dusty, unprimed surfaces. Either can make it fail early.

How to look after the new joints
After the cure time, these simple habits help:
- Avoid scourers and strong chemicals on sealant
- Do not wait for the house to settle if water is getting through
- Open a window or run the fan after bathing
- Report sealant problems to your builder during the snagging period
Avoid standing on the rim of the bath or the edge of the tray. If a bath or tray moves when you stand in it, get it looked at.
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.
What sealant work cannot fix
We’d rather tell you now than do work that won’t last, so these are the limits:
- Baths and trays that move too much for sealant to cope with
- Cracking that points to a structural problem
- Your warranty claim itself, which is between you and the builder
If you’re not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer before booking.
Surfaces we seal
- Windows & doors
- Plot handovers
- Show homes
- Skirting & floors
- Kitchens
- Bathrooms & en suites
Different surfaces, different methods
Plot handovers
Developers can send the plot schedule and specification and we’ll quote. We seal bathrooms, kitchens, frames and floors as agreed.
Kitchens
New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.
Can I do it myself?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
