New build mastic for homes and businesses in Leigh
Snagging sealant properly means taking the failed bead out completely. Fresh silicone cannot bond to the old layer, so the joint is cut out, cleaned, dried and resealed. Common call-outs are for joints pulling apart as timber shrinks and gaps between new skirting and floors, on skirting & floors, windows & doors and kitchens.
Around Leigh, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Big or small, you get the same one-year guarantee.

New homes and floors in Leigh
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you’ve bought a new home near Betchworth station, the sealant around baths, showers and frames is worth checking in the first year or two.

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Keep photos and emails about snagging items
- Keep water off fresh sealant until it has cured
- Do not wait for the house to settle if water is getting through
- Put sealant faults on your snagging list early
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
Leigh questions
Do you work for landlords with property near Betchworth station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Is Leigh within the area you cover?
Yes. Leigh is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you take on second-fix sealing for builders?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send the schedule and any specification and we will give you a quote.
Should I wait before resealing?
If the seal has failed and water is getting in, do it now. Small gaps that are just cosmetic can be resealed once movement has slowed.
Can you work from my snagging list?
Yes. We often work straight from a snagging list. We will go through the sealant items and agree what we will do.
How long does new build mastic take?
Most jobs take anything from a few hours to several days, depending on the number of plots, including preparation and clearing up. Your quote will say how long we expect yours to take.
Will the old sealant be removed?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

What else we do in Leigh
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. 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 chosen for how the joint moves and where it is.
Different surfaces, different methods
Plot handovers
Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing so the sealant lasts.
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant that suits the frame.
How we quote for new build mastic
We quote each job individually. These are the things that affect it:
- Whether old sealant or filler has to be cut out
- Whether there’s mould to deal with
- How many areas need sealing
- How much there is to do
The cost reflects the work involved, not guesswork. That is why we ask about the job first.
Asking for a quote
Before you ask for a quote, have a think about:
- What’s wrong with the joints now
- How many joints, rooms or windows are involved
- Photos by email, if that is easy
- Where the job is, and your postcode
There’s no standard price list. Instead, we send you a clear quote for your job. To get started, ring 0345 464 0079 or email us.
When to call us in Leigh
Sealant applied onto damp surfaces does not bond well. Site programmes do not always leave time for joints to dry.
Any of these means the joints need attention:
- Sealant applied over dusty or wet surfaces
- Gaps between new skirting and floors
- Smeared, uneven beads picked up at snagging
- Cracks appearing as a new home settles
In and around Leigh, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
