Questions from Lightwater
Do you work for landlords with property near Bagshot station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Can you do new build mastic in Lightwater?
Yes, Lightwater is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear price.
Should I go to my builder first?
Report it to the builder first while you’re covered. Once that’s done, or if they won’t put it right, we can reseal it properly.
Can you do plot mastic on a new development?
Yes. We seal plots to the developer’s programme. Tell us the plots and the joints involved and we will quote.
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.
Is there a guarantee?
Yes. Every job comes with a 12-month guarantee.
Why has my new-build shower seal failed already?
Cracking in the first couple of years is common as timber and plaster dry out. Rushed application on dusty surfaces makes it worse.
When is the best time to reseal in a new build?
It depends on whether water is getting through. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
New build mastic in Lightwater, done properly
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over using the right product for each joint. If you’re dealing with kitchen sealant that has pulled off the wall and joints pulling apart as timber shrinks, we can help, on windows & doors, show homes and skirting & floors alike.
In smaller places like Lightwater, new homes tend to come as small developments or single plots. Each still needs its sealant and floor joints finished properly from day one.
Every job is covered by a 12-month guarantee.

What affects the cost of new build mastic
You’ll get a clear quote before we start. It’s based on:
- How many rooms, windows or areas are involved
- Any working-time requirements on site
- How much old sealant there is and how hard it is to remove
- How easy the joints are to reach
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or send us an email for an honest opinion and a quote.
Asking for a quote
When you contact us, these details help:
- If someone has resealed it before
- What’s wrong with the joints now
- A few pictures by email, if you can
- Roughly how big the job is
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we will take it from there.
Why act early in Lightwater
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. Homes in smaller places like Lightwater can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What you get with us
- Domestic, commercial and hotel work
- Fully insured

When something else is needed
Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:
- Plumbing faults behind the sealant
- Deciding who is responsible under a builder’s warranty
- Movement caused by a poorly fitted tray or bath
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.

What the job involves on each surface
Kitchens
As a new house dries, worktops and walls shift a little, opening gaps behind the upstand. We reseal them with a flexible sealant.
Show homes
In a show home, the sealant is on display. We lay neat, even beads in colours to suit the finishes.
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can be quoted together.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
