New build mastic in Bulbourne
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly. We work on skirting & floors, plot handovers and show homes, and common reasons people get in touch are untidy sealant flagged on a snagging list and sealant that never bonded to the surface.
In a village or hamlet like Bulbourne, 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.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

What happens if it’s left?
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times. In a small place like Bulbourne, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.
Why book with us
- Sanitary silicone with an anti-fungal additive in wet areas
- Quality sealants from Arbo and Everbuild
- A choice of colours where the product allows
- You choose the colour before work begins

Looking after it afterwards
So the new joints stay in good condition:
- Act quickly if a seal starts to leak
- Clean sealant with mild detergent, not abrasives
- Follow the cure time we give you
- Look at the sealant regularly in the first couple of years
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing to help keep mould away.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in saves a harder job later.
Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
What the job involves on each surface
Kitchens
As a new house dries, worktops and walls shift a little, opening gaps behind the upstand. A fresh flexible bead closes them.
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
FAQs for Bulbourne

Is Bulbourne within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Is it worth resealing while the house is still settling?
It depends on whether water is getting through. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.

What we’re called out for in Bulbourne
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
Most people get in touch after spotting something like this:
- Cracked caulk along new skirting
- Cracked sealant around new window and door frames
- Joints pulling apart as timber shrinks
- Worktop and upstand sealant coming away
For new homes near Tring station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before you book
- How long the guarantee is
- Whether VAT is included
- Whether all the old sealant comes out first
- Which sealant they’ll use, and why
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll give you a quote.
What we do, step by step
Before we leave, we go over the finished joints with you and explain the cure time.
