How we handle new build mastic in Smith's Green
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. If you are still within the builder’s snagging or warranty period, tell them first, and if it isn’t put right, get in touch with us. Common call-outs are for leaking shower tray seals in a new home and gaps behind new kitchen upstands, across windows & doors, show homes and bathrooms & en suites.
Around Smith's Green, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

What happens if it’s left?
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times to plan around. Around Smith's Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
We work for landlords and letting agents as well as householders. Sealant work between tenants keeps a property looking cared for.

How much does new build mastic cost in Smith's Green?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
When is the best time to reseal in a new build?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Do you take on second-fix sealing for builders?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. We clean and prime joints properly to keep callbacks down.
What do you need from me for a quote?
Let us know what needs doing and where, plus photos if you have them. If we need more, we will ask.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
How the job changes by surface
Show homes
We can refresh show-home sealant that has discoloured or been knocked. We cut it out and reseal neatly.
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens.
What we’re called out for in Smith's Green
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Neither lasts long.
Keep an eye out for these signs:
- Gaps opening as the house dries out and settles
- Gaps between new skirting and floors
- Untidy sealant flagged on a snagging list
- Kitchen sealant that has pulled off the wall
In and around Smith's Green, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What to look for in a quote
- How the surfaces are prepared before sealing
- What the cure time is
- What insurance they hold
- Whether the sealant suits the joint
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
What sealant work cannot fix
We’d rather tell you now than do work that won’t last, so these are the limits:
- Deciding who is responsible under a builder’s warranty
- Plumbing faults behind the sealant
- A tray or bath that is not properly supported, until it’s fixed
If in doubt, ring 0345 464 0079 or email us and we will say what we think.
What we seal
