About our new build mastic in Langley Heath
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over with a sealant suited to each area. We are often asked to deal with skirting joints opening in the first winter and gaps opening as the house dries out and settles, across bathrooms & en suites, show homes and skirting & floors.
Somewhere as small as Langley Heath, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Landlords, agents and businesses in Langley Heath
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Letting agents and landlords in Langley Heath can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
How it works
We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Langley Heath, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property
Getting a quote
We quote each job on its own, so start by telling us what you need. Simply phone 0345 464 0079 or send us an email and describe the job.

Common problems we fix in Langley Heath
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak, and the problem shows up after you move in.
The problems people generally mention when they call include:
- Smeared, uneven beads picked up at snagging
- Internal frame sealant that has split
- Gaps behind new kitchen upstands
- Skirting joints opening in the first winter
Around Langley Heath, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before you book
- Which sealant they’ll use, and why
- How the joint is cleaned and prepared
- Whether you can choose the colour
- Who does the work, and how experienced they are
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Clean sealant with mild detergent, not abrasives
- Report sealant problems to your builder during the snagging period
- Get a leaking seal dealt with straight away
- Use the extractor fan every time you shower
Do not stand on the bath edge or the lip of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
Early snagging is easier snagging. Left alone, a small crack can become a leak in a busy bathroom.
When something else is needed
It helps to know what we cannot do too:
- Your warranty claim itself, which is between you and the builder
- Leaking fittings rather than failed sealant
- Settlement cracks that need a surveyor
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think before you book.

How we quote for new build mastic
You will get a clear quote before we start. It takes into account:
- Working hours on commercial sites
- How easy the joints are to reach
- How much there is to do
- The number of rooms or windows
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Asking for a quote
Before you ask for a quote, have a think about:
- Any access issues, like height or stairs
- Where the job is, and your postcode
- If it’s domestic, commercial or a hotel
- The problem you’ve noticed
There’s no standard price list. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or email us.
Why act early in Langley Heath
A quick bead over the top of the old sealant can look fine at first, but it can’t bond to what’s underneath. A lasting seal starts with removing the old one completely. Older cottages and farmhouses around Langley Heath can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or send us an email and we will talk you through it.
