Is there a guarantee on new build mastic in Gurnard?

Do you do commercial work?

Can you match the sealant colour to my new kitchen or bathroom?

How long will you be here?
As a guide, most jobs take anything from a few hours to several days, depending on the number of plots. Bigger jobs take longer, and we will say how long yours will take.
Can landlords and businesses book you?
Yes, we do. We work in homes, commercial premises and hotels, and we’re fully insured.
Do you work for developers?
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.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
New build mastic in Gurnard
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. If you have gaps between new skirting and floors and plot mastic for developers ahead of handover, we can put it right, on windows & doors, bathrooms & en suites and skirting & floors alike.
Somewhere as small as Gurnard, 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.
All of our work is guaranteed for twelve months, in Gurnard and everywhere else we cover.

When it is not the sealant
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Baths and trays that move too much for sealant to cope with
- Leaking fittings rather than failed sealant
- Settlement cracks that need a surveyor
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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 affects the quote in Gurnard
The quote reflects the job in front of us. We look at:
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
- Any mould that needs treating
- Whether the work is at height
The cost depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.
Asking for a quote
Before you ask for a quote, have a think about:
- The problem you’ve noticed
- Roughly how big the job is
- Photos by email, if that is easy
- Where the property is
Getting a quote is simple: let us know what needs doing and where. A few pictures by email make the job easier to understand.
New build mastic around Gurnard
Gurnard is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Whether the job is in Gurnard itself or nearby, the right material for each joint matters as much as a neat finish. Around Gurnard, as everywhere, new build mastic is only as good as the preparation behind it.

Different surfaces, different methods
Plot handovers
Developers can send the plot schedule and specification and we’ll quote. We seal bathrooms, kitchens, frames and floors as agreed.
Skirting and floors
Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.
What happens on the day
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the number of plots. Somewhere like Gurnard needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- 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.
- Each area is checked and left with its cure time.
Before we arrive
- Keep children and pets away from the work area
- Let us know about earlier repairs to the joints
- Let us know if you’ve seen damp or leaks

Why deal with it now?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it cannot bond to what’s underneath. A lasting seal starts with removing the old one completely. Around Gurnard, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
