New build mastic for homes and businesses in Churt
We work in new homes and on new-build sites across Churt. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. If you have gaps opening as the house dries out and settles and second-fix sealing on new plots, we can put it right, on windows & doors, show homes and bathrooms & en suites alike.
In a village or hamlet like Churt, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Looking after it afterwards
So the new joints stay in good condition:
- Put sealant faults on your snagging list early
- Check bath and shower seals every few months as the house settles
- Follow the cure time we give you
- Wipe joints with warm soapy water
Follow the cure time we give you before the area gets wet. Most silicones need around a day to cure enough for use.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant.
Why act early in Churt
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or is not dealt with, we can reseal it properly. Older cottages and farmhouses around Churt can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.

Your questions about new build mastic in Churt
I let a flat near Haslemere station. Can you help?
Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
Is Churt within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Why has my new-build shower seal failed already?
Cracking in the first couple of years is common as timber and plaster dry out. Rushed application on dusty surfaces makes it worse.
Is there any odour?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
How long before the joint can be used?
Cure times vary by product and the conditions. We tell you how long to leave it before we go.
How long will you be here?
That depends on how much there is to do, but most jobs take anything from a few hours to several days, depending on the number of plots. We will give you a better idea when we quote.
Will you just run a new bead over the existing one?
No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.
When something else is needed
We will always be straight with you, so here’s what new sealant won’t do:
- Leaking fittings rather than failed sealant
- Damaged fittings that need replacing
- Settlement cracks that need a surveyor
If in doubt, ring 0345 464 0079 or email us and we will say what we think before you book.
Surfaces we seal
- Kitchens
- Plot handovers
- Show homes

What affects the quote in Churt
For a quick quote, just ask. What matters most is:
- Any working-time requirements on site
- How many rooms, windows or areas are involved
- Whether the work is at height
- Mould in or behind the old joints
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and give you a clear price before we start.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- The rough size of the job
- Access, such as stairs, a lift or height
- Pictures of the joints, sent by email
- The problem you’ve noticed

How it works
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for most snagging lists, longer for a run of plots. Somewhere like Churt 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.
- Each joint is checked for movement before work begins.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Tell us if parking is tricky
- Try not to wet indoor joints just before the visit
- Tell us about any previous sealing or DIY attempts
