New build mastic in Mortimer West End
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks instead of bonding to the dust. We’re often asked to deal with untidy sealant flagged on a snagging list and sealant work across a run of new homes, across show homes, bathrooms & en suites and plot handovers.
Somewhere as small as Mortimer West End, 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 our work is covered by our 12-month guarantee, wherever you are in West Berkshire.

Common problems we fix in Mortimer West End
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart, and sealant that can’t keep up splits.
Signs it’s time to call us include:
- Sealant applied over dusty or wet surfaces
- Gaps behind new kitchen upstands
- Leaking shower tray seals in a new home
- Second-fix sealing on new plots
If you’ve bought a new home near Mortimer station, the sealant around baths, showers and frames is worth checking in the first year or two.

Honest limits
Sealant is not the answer to every problem, and we’ll tell you before work begins. It won’t solve:
- Plumbing faults behind the sealant
- A tray or bath that isn’t properly supported, until it’s fixed
- Cracking that points to a structural problem

Quotes for new build mastic in Mortimer West End
Some jobs are bigger than they look, and some smaller. The main factors:
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
- Working hours on commercial sites
- The size of the job
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, phone 0345 464 0079 or send us an email for an honest opinion and a quote.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- If someone has resealed it before
- What’s wrong with the joints now
- Photos by email, if that is easy
- Whether it’s a home or a business
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we will talk you through the work.
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Photograph failed sealant before it’s redone
- Look at the sealant regularly in the first couple of years
- Open a window or run the fan after bathing
- Act quickly if a seal starts to leak
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in saves a harder job later.
FAQs for Mortimer West End
Do you cover Mortimer West End for new build mastic?
Yes. Our work covers London and the South East, and Mortimer West End is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear price.
I let a flat near Mortimer station. Can you help?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Can you reseal over the builder’s sealant?
No. New silicone will not bond to old silicone, so sealing over the top fails quickly. We cut the old bead out completely.
Is it worth resealing while the house is still settling?
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.
Where are you based?
Our base is Crawley. We work across South East England, London and Scotland.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Is it normal for sealant to crack in a new home?
New homes dry out and move in their first couple of years, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.
Can you match the sealant colour to my new kitchen or bathroom?
We use white, clear or a colour to suit the finishes. Let us know your preference when you ask for a quote.
What the job involves on each surface
Skirting and floors
Wet-area floor joints need a flexible seal. They get a flexible, water-resistant sealant.
Kitchens
As a new house dries, worktops and walls shift a little, opening gaps behind the upstand. A fresh flexible bead closes them.
What happens on the day
Most of a good job is in the preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes anything from a few hours to several days, depending on the number of plots. Somewhere like Mortimer West End needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- A sealant chosen for each area goes in and is tooled smooth.
