New build mastic for homes and businesses in Mannings Heath
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. Common call-outs are for shower seals failing in the first year or two and gaps opening as the house dries out and settles, across skirting & floors, show homes and windows & doors.
Work in a small place like Mannings Heath just needs the journey and access planning, and once on site, the job is the same as anywhere.
Every job is covered by a 12-month guarantee.

How we quote for new build mastic
Call for a quick quote. The main things that affect it are:
- The old material and how stubborn it is
- Any working-time requirements on site
- How many areas need sealing
- The size of the job
Doing several joints on one visit normally makes better use of the time than several visits. We will give you a clear quote for the lot.
What we need to know
Photos help, but a description is a good start. Try to tell us:
- Any previous sealing or DIY work
- Roughly how big the job is
- Where the property is
- What’s wrong with the joints now
Every job is quoted individually, so start by telling us what you need. Just phone 0345 464 0079 or drop us an email with the details and send pictures if you have them.
Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What happens on the day
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before any work starts. The work usually takes anything from a few hours to several days, depending on the number of plots. Somewhere as small as Mannings Heath, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely, 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.
How to prepare
- Move anything stored near the joints
- Tell us about any water getting in
- On commercial sites, let us know about site rules

Advice
Why deal with it now?
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. In a small place like Mannings Heath, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and give you a clear price before any work starts.
Why Mannings Heath customers choose us
- Colour agreed with you before any work starts
- Quality sealants from Arbo and Everbuild
- Sanitary silicone with an anti-fungal additive in wet areas
- Any old sealant cut out fully, not covered over
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Wipe joints with warm soapy water
- Raise failed sealant with the developer while you are covered
- Do not wait for the house to settle if water is getting through
- Keep pictures and emails about snagging items
Watch the joints as the house settles. Small gaps can appear as the house dries.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
New build mastic around Mannings Heath
