Why it’s worth doing now in Tongwell
Small cosmetic gaps can wait for the house to settle, but a leaking seal cannot. If you are unsure which you have, ring 0345 464 0079 or send us an email with photos and we will give you a straight answer. In a small place like Tongwell, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will explain what it covers.
What you get with us
- A choice of colours where the product allows
- Quality sealants from Arbo and Everbuild
- Over 20 years’ experience

New build mastic in Tongwell
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. We’re often asked to deal with messy sealant that spoils new finishes and kitchen sealant that has pulled off the wall, across plot handovers, windows & doors and skirting & floors.
In a village or hamlet like Tongwell, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

Tongwell questions
Will you come out to Tongwell?
Yes, Tongwell is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Milton Keynes Central station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Can I send you my snagging list?
Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before we start.
Can new sealant go on top of the old bead?
No. The old sealant is cut out fully, the joint cleaned and primed where needed, before resealing.
Is it normal for sealant to crack in a new home?
Cracking in the first couple of years is common. Poor preparation at handover adds to it.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint.

When to call us in Tongwell
The first winter with the heating on dries a new home quickly. Gaps open along skirting, frames and worktops and cracks appear in the sealant.
The most common problems we see are:
- Gaps opening as the house dries out and settles
- Sealant that never bonded to the surface
- Cracked sealant around new window and door frames
- Skirting joints opening in the first winter
In and around Tongwell, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What your quote should include
- Whether you can choose the colour
- What product goes in the joint
- How long the guarantee is
- How the joint is cleaned and prepared
What affects the cost of new build mastic
The price is agreed before any work begins. It’s based on:
- How many rooms, windows or areas are involved
- Whether the work is at height
- Mould in or behind the old joints
- Any working-time requirements on site
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What to tell us for a quote
You do not need to know the technical terms. Just tell us:
- The rough size of the job
- Where the job is, and your postcode
- Whether it has been sealed before
- Pictures of the joints, sent by email

How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours in a single home, and the area is left clean. Somewhere like Tongwell 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 start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Tell us about any water getting in
- Clear the area around the work
- Mention any parking rules near the property
How to get a quote
We quote each job on its own, so start by telling us what you need. Just phone 0345 464 0079 or drop us an email with the details.
Related advice
Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What new build mastic looks like in Tongwell
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

When it isn’t the sealant
Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:
- Baths and trays that move too much for sealant to cope with
- Leaking fittings rather than failed sealant
- Disputes or warranty claims with your builder
