Why it’s worth doing now in Braishfield
DIY kits don’t solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. In a small place like Braishfield, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Combining jobs into one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Honest limits
It helps to know what we can’t do:
- Leaking fittings rather than failed sealant
- Cracking that points to a structural problem

How we quote for new build mastic
The price is agreed before any work begins. It’s based on:
- The type of sealant required
- Any mould that needs treating
- Whether the work is at height
- Whether old sealant or filler has to be cut out
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- Photos by email, if that is easy
- If someone has resealed it before
- The rough size of the job
- Any access issues, like height or stairs
For a quote, phone 0345 464 0079 or send us an email with the location and a short description of the problem. We’ll give you a clear quote before any work starts.
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
We also work for property managers and facilities teams in Braishfield and across Hampshire. We can quote a run of properties together, and we are fully insured.
Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

How much does new build mastic cost in Braishfield?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or send us an email and let us know what needs doing and where.
Is it normal for sealant to crack in a new home?
There are usually two causes: movement as the house dries and settles, and sealant laid onto dust without primer. Cutting it out and resealing properly fixes both.
Can landlords and businesses book you?
Yes. Domestic, commercial and hotel work are all part of what we do.
Surface by surface
Kitchens
Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. A fresh flexible bead closes them.
Windows and doors
A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.
How it works
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours in a single home. Somewhere like Braishfield needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Preparing for the visit
- Tell us if parking is tricky
- Mention any sign-in or site rules at work premises
- Keep children and pets away from the work area
