New build mastic in Corhampton
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. Common call-outs are for second-fix sealing on new plots and skirting joints opening in the first winter, on kitchens, bathrooms & en suites and skirting & floors.
Older homes in small places like Corhampton often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Questions from Corhampton
Do you cover Corhampton for new build mastic?
Yes. We work across London and the South East, and Corhampton is part of that. You can call 0345 464 0079 or send us an email and let us know what needs doing, and we will send you a clear quote.
Is there a guarantee on new build mastic in Corhampton?
All our work, in Corhampton and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Should I wait before resealing?
It depends on whether water is getting through. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
Why has my new-build shower seal failed already?
Cracking in the first couple of years is common, because the house is drying and settling. Poor preparation at handover adds to it.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints.
How do I get a quote for new build mastic in Corhampton?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.
My new home is still under warranty. Should I contact you?
While the snagging or warranty period runs, the builder should be your first contact. If they’re slow or the fix does not last, we can help.
What affects the quote in Corhampton
We quote each job individually. This is what makes a difference:
- The number of rooms or windows
- Any mould that needs treating
- How much there is to do
- The old material and how stubborn it is
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
Helping us quote
Before you ask for a quote, have a think about:
- Photos by email, if that’s easy
- Whether it’s a home or a business
- How we’d reach the joints
- The problem you’ve noticed
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we’ll talk you through the work before giving you a price.
What happens on the day
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the number of plots. In a small place like Corhampton, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- Clear items away from the joints we’re working on
- Keep children and pets away from the work area
- For indoor joints, keep the area dry beforehand if you can

Advice
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Follow the cure time we give you
- Open a window or run the fan after bathing
- Avoid scourers and strong chemicals on sealant
- Photograph failed sealant before it’s redone
Leave the sealant for the cure time we give you before showering or bathing. Silicone is normally left for about a day to cure enough for use.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you so report it promptly.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Common problems we fix in Corhampton
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints aren’t always given time to dry before the sealant goes on.
Keep an eye out for any of the following:
- New-build shower sealant that has already split
- Sealant applied over dusty or wet surfaces
- Cracked sealant around new window and door frames
- Untidy sealant flagged on a snagging list
In and around Corhampton, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
