New build mastic in Dunton Green
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. If you’re dealing with messy sealant that spoils new finishes and gaps between new skirting and floors, we can help.
Around Dunton Green, 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.
There’s a 12-month guarantee on every job, large or small.

When to call us in Dunton Green
Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints are not always given time to dry.
Look out for any of the following:
- Messy sealant that spoils new finishes
- Shower seals failing in the first year or two
- Internal frame sealant that has split
- Skirting joints opening in the first winter
In and around Dunton Green, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours in a single home and we leave things clean and tidy. In a small place like Dunton Green, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.
Before we arrive

Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Why act early in Dunton Green
Resealing everything on a snagging list in one visit is normally simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times. Around Dunton Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we’ll go through it with you.

Looking after it afterwards
Looking after new joints is easy:
- Ventilate bathrooms well, especially in the first year
- Clean sealant with mild detergent, not abrasives
- Watch for new gaps as the house dries out
- Keep water off fresh sealant until it has cured
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents as they wear the bead.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
Your questions about new build mastic in Dunton Green
Can you do new build mastic in Dunton Green?
Yes, Dunton Green is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
Is Dunton Green within the area you cover?
Yes. Dunton Green is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Will the old sealant be removed?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Do you work through snagging lists?
Yes. Send us the sealant items on the list, with photos if you can and we will give you a quote. We will flag anything that needs another trade.
How much does new build mastic cost in Dunton Green?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Is it normal for sealant to crack in a new home?
Lots of new homes see sealant crack early as timber and plaster dry out. Rushed application on dusty surfaces makes it worse.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Is it worth resealing while the house is still settling?
Any seal that’s leaking should be redone right away. Cosmetic gaps can wait until the first year or two of movement has passed.
Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
