New build mastic for homes and businesses in Swalcliffe
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. We work on windows & doors, plot handovers and kitchens, and people most often call us about sealant that never bonded to the surface and gaps opening as the house dries out and settles.
For a small place like Swalcliffe, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
A 12-month guarantee comes as standard.

How it works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes a few hours for most snagging lists, longer for a run of plots, including the tidy-up. Somewhere like Swalcliffe needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked for movement before any work starts.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any previous sealing or DIY attempts

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, phone 0345 464 0079 or send us an email.

Swalcliffe: your questions answered
Do you cover smaller places like Swalcliffe?
Yes. Swalcliffe is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is new build mastic in Swalcliffe guaranteed?
All our work, in Swalcliffe and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
How do I get a quote for new build mastic in Swalcliffe?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Do the sealants smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Do you use white or clear sealant?
We use white, clear or a colour to suit the finishes. Tell us what you’d like when you get a quote.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or email us.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Movement caused by a poorly fitted tray or bath
- Cracking that points to a structural problem
- Your warranty claim itself, which is between you and the builder
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before booking.

Keeping the joints in good condition
Aftercare is simple:
- Look at the sealant regularly in the first couple of years
- Ventilate bathrooms well, especially in the first year
- Wipe joints with warm soapy water
- Report sealant problems to your builder during the snagging period
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you, so raise it early.
Landlord and commercial work in Swalcliffe
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will give you a quote.
New homes and floors in Swalcliffe
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Should I try it myself first?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Leave it or put it right?
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time. In a small place like Swalcliffe, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

When to call us in Swalcliffe
Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly and it shows once the home is in use.
Look out for any of the following:
- Gaps between new skirting and floors
- Second-fix sealing on new plots
- Worktop and upstand sealant coming away
- Gaps opening as the house dries out and settles
For jobs in and around Swalcliffe, choosing the right material for each joint is as important as a tidy finish.

- Is the old sealant removed completely?
