How we handle new build mastic in Heath End
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 rather than sitting on a layer of grit. We work on plot handovers, skirting & floors and kitchens, and people most often call us about plot mastic for developers ahead of handover and leaking shower tray seals in a new home.
In a village or hamlet like Heath End, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
Big or small, it’s backed by our one-year guarantee.

FAQs for Heath End
Is Heath End within the area you cover?
Yes, Heath End is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
I let a flat near Aldershot station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Do you remove the old sealant?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
How long before the joint can be used?
It depends on the product. Before we leave, we’ll tell you the cure time.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Will there be a smell?
Some sealants have a smell while they cure. Ventilation helps.
My new home is still under warranty. Should I contact you?
If you are still within the builder’s snagging or warranty period, report it to them first. If it isn’t sorted, or keeps failing, get in touch with us.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
What the job involves on each surface
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. The joint is stripped back before the new bead goes in.
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk painted or coloured to suit.
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Put sealant faults on your snagging list early
- Watch for new gaps as the house dries out
- Keep photos and emails about snagging items
- Act quickly if a seal starts to leak
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
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.
New homes and floors in Heath End
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

- Movement caused by a poorly fitted tray or bath

- Settlement cracks that need a surveyor

How it works
We keep the work tidy and contained to the area we are working on, so you can get on with your day. Expect the work to take a few hours for most snagging lists, longer for a run of plots, and we tell you how long to leave it before we go. In a small place like Heath End, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely, with no layer left behind.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- For business premises, tell us about site rules or sign-in
- Clear the area around the work

Why deal with it now?
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 Heath End, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Ask us for a quote and we’ll go through it with you.

When to call us in Heath End
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly, and the problem shows up after you move in.
Keep an eye out for these signs:
- Kitchen sealant that has pulled off the wall
- Joints pulling apart as timber shrinks
- Cracked sealant around new window and door frames
- Gaps between new skirting and floors
For new homes near Aldershot station, it’s worth checking the sealant early, while snags are still fresh.
