How we handle new build mastic in Foulford
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly instead of bonding to the dust. We’re often asked to deal with sealant that never bonded to the surface and sealant work across a run of new homes, on kitchens, show homes and skirting & floors.
Around Foulford, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
We stand behind the work with a 12-month guarantee, so you’re covered after we have gone.

Joints and finishes in Foulford homes

Around Foulford, as everywhere, new build mastic is only as good as the preparation behind it. Whether the job is in Foulford itself or nearby, the right material for each joint matters as much as a neat finish.

Why act early in Foulford
A quick bead over the top of the old sealant can look fine at first, but it won’t bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. In a small place like Foulford, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or email us and we will give you an honest view and a quote.

Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish. Tell us when the home is open so we can plan around it.
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.
Questions from Foulford
Is Foulford within the area you cover?
Yes. Foulford is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is there a guarantee on new build mastic in Foulford?
All our work, in Foulford and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Foulford and the rest of Hampshire.
Why does sealant fail so quickly in new builds?
Cracking in the first couple of years is common as timber and plaster dry out. Rushed application on dusty surfaces makes it worse.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Can you reseal over the builder’s sealant?
No. The old sealant is cut out fully, the joint cleaned and primed where needed, before resealing.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep pictures and emails about snagging items
- Avoid scourers and strong chemicals on sealant
- Do not wait for the house to settle if water is getting through
- Follow the cure time we give you
Follow the cure time we give you before the area gets wet. Most silicones need around a day before water reaches them.
Report failed sealant to the builder while you are in the snagging period. Once it ends, the repair may be down to you, so raise it early.
How the visit works
We keep the work tidy and contained to the area we are working on, so you can get on with your day. The job usually takes 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 Foulford, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you’re given the cure time.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Tell us about access, such as stairs, a lift or high-level joints
- On commercial sites, let us know about site rules
