Signs you need new build mastic in Falmer
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.
Look out for any of the following:
- Untidy sealant flagged on a snagging list
- New-build shower sealant that has already split
- Worktop and upstand sealant coming away
- Beads laid onto grit and dust from the build
If you’ve bought a new home near Falmer station, the sealant around baths, showers and frames is worth checking in the first year or two.
Before booking anyone
- How the joint is cleaned and prepared
- What product goes in the joint
- When the joint can take water or movement
- Whether all the old sealant comes out first
About our new build mastic in Falmer
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that’s reasonable, but a seal that’s letting water through needs doing now. Common call-outs are for skirting joints opening in the first winter and sealant that never bonded to the surface, on windows & doors, kitchens and bathrooms & en suites.
Somewhere as small as Falmer, 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.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Questions from Falmer
I let a flat near Falmer station. Can you help?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.
Is Falmer within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Are you insured?
Yes. We’re fully insured, and we have been doing sealant work for more than 20 years.
What do you need from me for a quote?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or drop us an email.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
How long will you be here?
It depends on the size of the job, but as a guide it takes a few hours in a single home. We’ll tell you when we quote.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
What affects the cost of new build mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- Any mould that needs treating
- How many areas need sealing
- How easy the joints are to reach
- The type of sealant required
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.
What we need to know
To make quoting easier, let us know:
- Where the job is, and your postcode
- Any access issues, like height or stairs
- Whether it’s a home or a business
- Photos by email, if that is easy
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Advice
Keeping the joints in good condition
Looking after new joints is easy:
- Record problems with dated pictures
- Follow the cure time we give you
- Put sealant faults on your snagging list early
- Do not seal over failed sealant yourself
Do not stand on the bath edge or the lip of the tray while the sealant cures. Report any movement in a bath or tray.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black saves a harder job later.
What the job involves on each surface
Show homes
We can refresh show-home sealant that has discoloured or been knocked. The old bead comes out and a clean new one goes in.
Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it in a colour to suit.

We work for landlords and agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
