New build mastic for homes and businesses in Selsted
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. If you are dealing with messy sealant that spoils new finishes and gaps behind new kitchen upstands, we can put it right.
Somewhere as small as Selsted, 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.
A 12-month guarantee comes as standard.

Questions from Selsted
I let a flat near Shepherds Well station. Can you help?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Do you cover Selsted for new build mastic?
Yes. Our work covers London and the South East, and Selsted is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
Can you do plot mastic on a new development?
Yes. We take on second-fix sealant work across new plots. We clean and prime joints properly to keep callbacks down.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Is there a guarantee?
Yes. Every job comes with a 12-month guarantee.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
What colour sealant will you use?
White and clear are the most common, but other colours are available. We match the colour to the finish and agree it with you.
Will the old sealant be removed?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Different surfaces, different methods
Kitchens
Sink joints are wet all the time. A kitchen sealant goes in there.
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.

What affects the cost of new build mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- Any working-time requirements on site
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
- The old material and how stubborn it is
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Where the property is
- A few pictures by email, if you can
- Whether it’s a home or a business
- What the problem is, such as mould, gaps, leaks or cracking
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.
What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Movement caused by a poorly fitted tray or bath
- Disputes or warranty claims with your builder
- Leaks from pipes, valves or wastes, which need a plumber
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.
