New build mastic for homes and businesses in The Willows
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. Common call-outs are for sealant work across a run of new homes and beads laid onto grit and dust from the build, across show homes, bathrooms & en suites and plot handovers.
Somewhere as small as The Willows, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

What else we do in The Willows
Why deal with it now?
A quick bead over the top of the old sealant can look fine at first, but it can’t bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. In a small place like The Willows, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

How we quote for new build mastic
For a quick quote, just ask. What matters most is:
- Whether old sealant or filler has to be cut out
- Whether the work is at height
- The size of the job
- Working hours on commercial sites
We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or drop us an email and we’ll talk you through it.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- Any access issues, like height or stairs
- If someone has resealed it before
- If it’s domestic, commercial or a hotel
- Pictures of the joints, sent by email
To get a quote, phone 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. We will give you a clear price before any work starts.
Looking after it afterwards
To keep the joints looking good and working properly:
- Put sealant faults on your snagging list early
- Use the extractor fan every time you shower
- Wait for the cure time before using a resealed shower
- Don’t wait for the house to settle if water is getting through
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents as they wear the bead.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
For landlords and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
Different surfaces, different methods
Show homes
We seal show-home bathrooms, kitchens and frames. Tell us when the home is open so we can plan around it.
Kitchens
New-kitchen sealant is often applied in a rush. We remove it and reseal with a kitchen-suitable sealant.
