New Build Mastic in Holmethorpe
We cover Holmethorpe for plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- New-build shower sealant that has already split
- Sealant that never bonded to the surface
- Cracked caulk along new skirting
Common problems we fix in Holmethorpe
A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open, and sealant that can’t keep up splits.
It’s worth asking for a quote if you see:
- Sealant work across a run of new homes
- Cracked sealant around new window and door frames
- Gaps opening as the house dries out and settles
- Messy sealant that spoils new finishes
For new homes near Redhill station, it’s worth checking the sealant early, while snags are still fresh.
What to look for in a quote
- How long to leave it before use
- Whether all the old sealant comes out first
- What insurance they hold

New build mastic for homes and businesses in Holmethorpe
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. If you have second-fix sealing on new plots and cracked sealant around new window and door frames, we can put it right, whatever the surface.
In and around Holmethorpe, floors range from older timber boards to tiles and newer finishes, from timber that moves with the seasons to tiles laid on concrete. Skirting and threshold joints need a sealant that suits the floor.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Leave it or put it right?
The builder is usually the first port of call while the snagging or warranty period runs. If it keeps failing or is not dealt with, we can reseal it properly. Around Holmethorpe, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before any work starts, so you know where you stand.
Why us?
- Colour picked to suit the job
- Sanitary silicone with an anti-fungal additive in wet areas
- Neat joints and a tidy finish
- More than 20 years in sealant work

FAQs for Holmethorpe
Is Holmethorpe in your area for new build mastic?
Yes. Our work covers London and the South East, and Holmethorpe is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.
Do you work for landlords with property near Redhill station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.
Is it normal for sealant to crack in a new home?
It’s common, and there are usually two reasons: the house moving as it dries, and sealant that never bonded properly. A proper reseal deals with both.
What should I tell you?
A short description and the location, plus pictures if you have them. If we need more, we will ask.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Work for landlords, hotels and businesses
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.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
How to look after the new joints
To keep the joints looking good and working properly:
- Clean sealant with mild detergent, not abrasives
- Act quickly if a seal starts to leak
- Put sealant faults on your snagging list early
- Check bath and shower seals every few months as the house settles
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry and can be resealed later.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and the new finishes intact.
The process
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours in a single home. In a smaller place like Holmethorpe, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- 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 parking restrictions
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any water getting in
