New Build Mastic in Heyshott
Problem with your new-build sealant joints in Heyshott? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Untidy sealant flagged on a snagging list
- Cracks appearing as a new home settles
- Cracked caulk along new skirting
How we handle new build mastic in Heyshott
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so it all comes out before we clean, dry and reseal. If you’re dealing with gaps behind new kitchen upstands and beads laid onto grit and dust from the build, we can put it right, whatever the surface.
Somewhere as small as Heyshott, 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.

Common questions in Heyshott
Is Heyshott in your area for new build mastic?
Yes, Heyshott is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.
What guarantee comes with new build mastic in Heyshott?
All our work, in Heyshott and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Can new sealant go on top of the old bead?
No. We always remove the existing bead, then clean and prime the joint, before resealing.
How do I get a quote for new build mastic in Heyshott?
It depends on the job, so we quote each one individually. To get one, ring 0345 464 0079 or drop us an email and let us know what needs doing and where.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
How long does the job take?
That depends on the amount of work, but most jobs take a few hours in a single home. We’ll give you a better idea when we quote.
What happens on the day
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Heyshott, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts
- Tell us if parking is tricky

Different surfaces, different methods
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. We reseal them with a flexible sealant.
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk in a colour to suit.
What new build mastic looks like in Heyshott
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For jobs in and around Heyshott, choosing the right material for each joint is as important as a tidy finish.

How we quote for new build mastic
The price is agreed before any work begins. It takes into account:
- Whether the work is at height
- How much there is to do
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.
Asking for a quote
Photos help, but a description is a good start. Please mention:
- Roughly how big the job is
- Access, such as stairs, a lift or height
- Photos by email, if that is easy
- What the problem is, such as mould, gaps, leaks or cracking
To get a quote, phone 0345 464 0079 or send us an email with the location and a short description of the problem. We will give you a clear price before any work starts.
Common problems we fix in Heyshott
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes don’t always leave time for joints to dry before the sealant goes on.
It’s worth asking for a quote if you see:
- Cracks appearing as a new home settles
- Shower seals failing in the first year or two
- Gaps between new skirting and floors
- Gaps behind new kitchen upstands
In and around Heyshott, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Before you book anyone

- Whether the sealant suits the joint

- How the joint is cleaned and prepared
What else we do in Heyshott
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Avoid scourers and strong chemicals on sealant
- Raise failed sealant with the developer while you are covered
- Keep water off fresh sealant until it has cured
- Resist patching a failed seal with a tube from the DIY shop
Follow the cure time we give you before the area gets wet. Silicone is generally left for about a day.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
For landlords and businesses
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Landlords and letting agents in Heyshott can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
Why deal with it now?
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time and most come down to preparation. Where a wall is exposed, as many are in small places like Heyshott, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts.
