New build mastic in Farnborough
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. Both get the same care over preparation since hurried prep is behind a lot of new-build failures. If you are dealing with internal frame sealant that has split and cracks appearing as a new home settles, we can help, whatever the surface.
Homes around Farnborough move a little with the seasons, and skirting and floor joints show it first. Those joints need a flexible sealant, as rigid filler soon cracks out.
You’re covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or drop us an email.

What we do, step by step
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes a few hours for most snagging lists, longer for a run of plots from start to finish. For a job in Farnborough, we need access to where the work is and somewhere nearby to park. If the job is outside, mention gates, side access and anything above ground floor.
- Each joint is checked for movement before we start.
- 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.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Mention any tricky access
- Mention any sign-in or site rules at work premises

What the job involves on each surface
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.
Kitchens
As a new house dries, worktops and walls shift a little, opening gaps behind the upstand. We reseal them with a flexible sealant.

When to call us in Farnborough
A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart and the sealant has to cope with the movement.
People usually contact us when they notice something like this:
- Worktop and upstand sealant coming away
- Cracked sealant around new window and door frames
- Second-fix sealing on new plots
- Skirting joints opening in the first winter
Around Farnborough, as everywhere, new build mastic is only as good as the preparation behind it.

- Is the old sealant removed completely?
Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

How we quote for new build mastic
The price is agreed before any work begins. It takes into account:
- The old material and how stubborn it is
- Working hours on commercial sites
- Which sealant suits the joint
- Whether there’s mould to deal with
The cost reflects the work involved, not guesswork. That is why we ask about the job first.

Photos help, but a description is a good start. Try to tell us:
- What’s wrong with the joints now
- Photos by email, if that is easy
- How we’d reach the joints
