New Build Mastic in Roehampton
Problem with your new-build sealant joints in Roehampton? We cut out the old, prepare the joints and apply the right sealant.
- Plot mastic for developers ahead of handover
- New-build shower sealant that has already split
- Gaps between new skirting and floors
How we handle new build mastic in Roehampton
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. We work on bathrooms & en suites, skirting & floors and windows & doors, and common reasons people get in touch are gaps opening as the house dries out and settles and plot mastic for developers ahead of handover.
Across London, commercial floors have movement joints that break down under heavy foot traffic, while new homes need a neat, sound finish around frames, baths and kitchens before handover, in Roehampton and beyond.
Whatever the size of the job, you get the same one-year guarantee.

Landlords, agents and businesses in Roehampton
We work for landlords and agents as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
What we are called out for in Roehampton
The first winter with the heating on dries a new home quickly. Gaps open along skirting, frames and worktops and cracks appear in the sealant.
Most people get in touch when they notice one of these:
- Beads laid onto grit and dust from the build
- Gaps between new skirting and floors
- Gaps opening as the house dries out and settles
- Gaps behind new kitchen upstands
As a London address, Roehampton can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
Questions to ask before you book
- Who does the work, and how experienced they are
- What the cure time is
- Is VAT in the price?
- Is the old sealant removed completely?
New build mastic in Roehampton: local notes
Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you’ve bought a new home near Barnes station, the sealant around baths, showers and frames is worth checking in the first year or two.

How we quote for new build mastic
We quote each job individually. This is what makes a difference:
- Whether old sealant or filler has to be cut out
- How many areas need sealing
- Mould in or behind the old joints
- How easy the joints are to reach
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.
Helping us quote
To help us quote quickly, let us know:
- Any previous sealing or DIY work
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking
- Roughly how big the job is
To get a quote, phone 0345 464 0079 or email us and tell us where the job is and what the problem looks like. You’ll have a clear quote before any work starts.
How the visit works
The work is kept neat and contained to the area we’re working on, so you can carry on as normal. Expect the work to take a few hours in a single home, and we explain the cure time before we leave. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Roehampton. It helps if you can point us to a visitor permit or a bay close to the door.
- First we work through your snagging list or plot schedule with you.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Each area is checked and left with its cure time.
Preparing for the visit
- Mention any parking rules near the property
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area
How to get a quote
Getting a quote is simple: tell us what needs doing and where and its rough size. A few pictures by email make the job easier to understand, and we will come back to you with a quote.

How the job changes by surface
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. The joint is stripped back before the new bead goes in and baths are filled before sealing.
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.
What we can’t put right
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Leaking fittings rather than failed sealant
- Cracked trays, tiles or worktops
- Settlement cracks that need a surveyor
If in doubt, call 0345 464 0079 or send us an email and we will say what we think before booking.

Roehampton: your questions answered
Is parking an issue for new build mastic in Roehampton?
Parking in Roehampton, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
I let a flat near Barnes station. Can you help?
Yes, we work for letting agents and landlords. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before resealing.
Is it worth resealing while the house is still settling?
That depends on the joint. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
Do you have insurance?
Yes, we are fully insured for domestic and commercial work.
How long does new build mastic take?
A typical job takes a few hours in a single home, including preparation and clearing up. Your quote will say how long we expect yours to take.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
How long before the joint can be used?
That depends on the sealant used, so please follow the time we give you.
Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
