About our new build mastic in Wyatt's Green
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. We work on plot handovers, bathrooms & en suites and kitchens, and the jobs we see most are plot mastic for developers ahead of handover and cracked sealant around new window and door frames.
Somewhere as small as Wyatt's Green, 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.
You get a one-year guarantee, the same in Wyatt's Green as everywhere else we work.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
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.
When to call us in Wyatt's Green
The wrong product is sometimes used in the wrong place: caulk where water collects, or a rigid product on a moving joint. Neither lasts long.
Signs it’s time to call us include:
- Untidy sealant flagged on a snagging list
- Sealant applied over dusty or wet surfaces
- Gaps between new skirting and floors
- Gaps behind new kitchen upstands
In and around Wyatt's Green, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes anything from a few hours to several days, depending on the number of plots.

- Each joint is checked for movement before we start.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.

How the job changes by surface
Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk in a colour to suit.
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in with baths filled first.

How to look after the new joints
So the new joints stay in good condition:
- Ventilate bathrooms well, especially in the first year
- Keep pictures and emails about snagging items
- Report sealant problems to your builder during the snagging period
- Don’t wait for the house to settle if water is getting through
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers to help keep mould away.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.

Can you help a landlord with a rental near Shenfield station?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
Can you do new build mastic in Wyatt's Green?

Yes. Every job comes with a one-year guarantee.
My new home is still under warranty. Should I contact you?
Start with your builder while their snagging or warranty period runs. After that, or if their repair keeps failing, we can do it.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will explain our choice.
Do you take on second-fix sealing for builders?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send us the plot schedule and we will quote.
When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Leaking fittings rather than failed sealant
- Deciding who is responsible under a builder’s warranty
- Cracked trays, tiles or worktops
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly.

Why deal with it now?
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. Around Wyatt's Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
