From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.

About our new build mastic in Stamford Hill
For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover using the right product for each joint. We are often asked to deal with smeared, uneven beads picked up at snagging and leaking shower tray seals in a new home, across skirting & floors, windows & doors and bathrooms & en suites.
London homes range from new-build flats to period conversions with new floors laid over old boards. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement, in Stamford Hill as anywhere.
Big or small, it’s backed by our 12-month guarantee in Stamford Hill and across Greater London.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Look at the sealant regularly in the first couple of years
- Do not wait for the house to settle if water is getting through
- Keep water off fresh sealant until it has cured
- Raise failed sealant with the developer while you’re covered
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing so moisture does not sit on the sealant.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
Stamford Hill questions
Is Stamford Hill in your area for new build mastic?
Yes, Stamford Hill is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
I let a flat near Stamford Hill station. Can you help?
Yes, we work for landlords and agents. Just call 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
Is it normal for sealant to crack in a new home?
It’s common, and there are generally two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us and we are fully insured.
Will there be a smell?
Some sealants have a smell while they cure. Opening a window helps.
Do you work for developers?
Yes. We seal plots to the developer’s programme, room by room. Get in touch with the number of plots and the scope and we’ll quote.
How long does new build mastic take?
That depends on the amount of work, but most jobs take anything from a few hours to several days, depending on the number of plots. We’ll tell you when we quote.
Is there a guarantee?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from a few hours to several days, depending on the number of plots and we leave things clean and tidy. In Stamford Hill, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely down to clean surfaces.

- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Tell us about any water getting in
- Clear items away from the joints we’re working on
- Mention any sign-in or site rules at work premises

Advice
Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Joints and finishes in Stamford Hill homes
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. Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent.
For new homes near Stamford Hill station, it’s worth checking the sealant early, while snags are still fresh.

What the job involves on each surface
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing and primer used where needed.
