New build mastic in Tangmere, done properly
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. If you have leaking shower tray seals in a new home and sealant that never bonded to the surface, we can put it right.
If you’ve bought a new home in or near Tangmere, the first year or two is a good time to check the sealant. Common snags include open skirting joints, lifting shower seals and gaps around frames.
All our work is covered by our one-year guarantee.

Why it’s worth doing now in Tangmere
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 Tangmere can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will explain what it covers.

How it works
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for most snagging lists, longer for a run of plots. In a smaller place like Tangmere, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work

What we are called out for in Tangmere
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart and the sealant has to cope with the movement.
Most people get in touch after spotting something like this:
- Second-fix sealing on new plots
- Skirting joints opening in the first winter
- Untidy sealant flagged on a snagging list
- Kitchen sealant that has pulled off the wall
If you’ve bought a new home near Chichester station, the sealant around baths, showers and frames is worth checking in the first year or two.

Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Avoid running a DIY bead over the old one
- Photograph failed sealant before it’s redone
- Ventilate bathrooms well, especially in the first year
- Follow the cure time we give you
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Questions from Tangmere
Will you come out to Tangmere?
Yes. Tangmere is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do new build mastic in Tangmere?
Yes, Tangmere 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.
Will the old sealant be removed?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
Can you match the sealant colour to my new kitchen or bathroom?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before we start.
Do you work for developers?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send us the plot schedule and we’ll quote.
Why does sealant fail so quickly in new builds?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.
My new home is still under warranty. Should I contact you?
Start with the builder if you’re in the snagging or warranty period. If it is not resolved, we can reseal it properly.
Do you work for landlords and businesses?
Yes. As well as householders, we work for landlords, agents, businesses and hotels.
Different surfaces, different methods
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish. We will plan around viewing times.
Plot handovers
