- Smeared, uneven beads picked up at snagging
What the job involves on each surface
Plot handovers
Send us the schedule and any sealant specification and we’ll quote. Sealant work across the plot is covered.
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. We reseal it with a weatherproof, flexible sealant.
New build mastic in Calbourne, done properly
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so the joint is cut out, cleaned, dried and resealed. If you are dealing with joints pulling apart as timber shrinks and gaps between new skirting and floors, we can help, whatever the surface.
Somewhere as small as Calbourne, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
You are covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or send us an email.

Joints and finishes in Calbourne homes
Calbourne is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Around Calbourne, as everywhere, new build mastic is only as good as the preparation behind it.

Why act early in Calbourne
A quick bead over the top of the old sealant can look fine at first, but it can’t bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. In a small place like Calbourne, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

FAQs for Calbourne
Is Calbourne in your area for new build mastic?
Yes. We work across London and the South East, and Calbourne is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear price.
Do you cover smaller places like Calbourne?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do plot mastic on a new development?
Yes. We seal plots to the developer’s programme. Tell us the plots and the joints involved for a clear quote.
Should I go to my builder first?
Start with your builder while their snagging or warranty period runs. After that, or if their repair keeps failing, we can do it with our 12-month guarantee.
Can I add another job to the visit?
Yes. Just list everything you need.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Is there a guarantee?
Yes. Each job is guaranteed for twelve months.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
What we cannot put right
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Settlement cracks that need a surveyor
- A tray or bath that is not properly supported, until it’s fixed
- Damaged fittings that need replacing
If in doubt, call 0345 464 0079 or email us and we’ll say what we think before booking.

Do you need new build mastic in Calbourne?
Sealant is often one of the last jobs before handover. Joints are not always cleaned of dust or primed, so the bead never bonds properly.
It’s worth asking for a quote if you see:
- Smeared, uneven beads picked up at snagging
- Joints pulling apart as timber shrinks
- New-build shower sealant that has already split
- Skirting joints opening in the first winter
For jobs in and around Calbourne, choosing the right material for each joint is as important as a tidy finish.

How the visit works
On the day, we look over the joints with you first. We protect the surfaces around the joints before work begins. The work usually takes a few hours in a single home.

Everything for the job comes with us, so a second trip is avoided where possible.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Preparing for the visit

- Tell us about any water getting in
- Let us know about earlier repairs to the joints

Landlords, agents and businesses in Calbourne
For anyone letting property in or around Calbourne, several properties can be quoted together. Send us the addresses and the work at each.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Aftercare tips
To keep the joints looking good and working properly:
- Do not seal over failed sealant yourself
- Raise failed sealant with the developer while you are covered
- Keep water off fresh sealant until it has cured
- Check bath and shower seals every few months as the house settles
Leave the sealant for the cure time we give you before showering or bathing. Silicone is normally left for about a day to cure enough for use.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
