New build mastic for homes and businesses in Frogmore
Across Frogmore, we work for both new-home owners and the builders handing those homes over. Whether it’s one en suite or a run of plots, the method is the same: remove, clean, prime where needed, then a neat new bead. If you’re dealing with second-fix sealing on new plots and sealant that never bonded to the surface, we can help.
Where new homes go up in smaller places like Frogmore, it’s often a small development or a single plot. Each still needs its sealant and floor joints finished properly from day one.
We stand behind the work with a one-year guarantee.

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Keep pictures and emails about snagging items
- Follow the cure time we give you
- Open a window or run the fan after bathing
- Report sealant problems to your builder during the snagging period
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it.
Don’t let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you, so raise it early.
How we quote for new build mastic
Call for a quick quote. The main things that affect it are:
- How many rooms, windows or areas are involved
- How much there is to do
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
Doing several joints on one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.
Helping us quote
You don’t need to know the technical terms. Just tell us:
- Whether it has been sealed before

Common questions in Frogmore
Do you work for landlords with property near Sandhurst station?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Do you cover Frogmore for new build mastic?
Yes. Our work covers London and the South East, and Frogmore is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing, and we’ll send you a clear quote.
Do you guarantee your work?
Yes. Every job comes with our one-year guarantee.
Do you work through snagging lists?
Yes. Send it with photos and we will quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
Can you reseal over the builder’s sealant?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before work begins.
Do you work for developers?
Yes. We seal plots to the developer’s programme ready for handover. Tell us the plots and the joints involved and we will quote.
When is the best time to reseal in a new build?
That depends on the joint. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
What does new build mastic cost?
It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or send us an email and let us know what needs doing and where.
Common problems we fix in Frogmore
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
Common reasons people contact us include:
- Joints pulling apart as timber shrinks
- Sealant applied over dusty or wet surfaces
- Skirting joints opening in the first winter
- Sealant work across a run of new homes
Around Frogmore, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before booking
- How hidden problems are handled
- Is VAT in the price?
- How the surfaces are prepared before sealing
- What product goes in the joint
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
The process
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for most snagging lists, longer for a run of plots. A visit to Frogmore is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Before we arrive
- Let us know about earlier repairs to the joints
- For indoor joints, keep the area dry beforehand if you can
- Keep pets and children clear of the area while we work

Advice
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Joints and finishes in Frogmore homes
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you’ve bought a new home near Sandhurst station, the sealant around baths, showers and frames is worth checking in the first year or two.

Why act early in Frogmore
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. In an older home around Frogmore, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
