New build mastic in Wyck, 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 gets into the floor or walls. We are often asked to deal with plot mastic for developers ahead of handover and sealant applied over dusty or wet surfaces, on windows & doors, plot handovers and skirting & floors.
For a small place like Wyck, the journey and access are planned in advance, and the work itself is the same as on any site.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
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.
How the visit works
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours in a single home. Somewhere as small as Wyck, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- 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.
Before we arrive
- Try not to wet indoor joints just before the visit
- Let us know if you’ve seen damp or leaks
- Let us know about parking restrictions
How to get a quote
Getting a quote is simple: let us know what needs doing and where. Photos by email help us understand the job, and we’ll take it from there.
Advice
What we cannot put right
To be straight with you, there are a few things sealant will not fix:
- Baths and trays that move too much for sealant to cope with
- Cracking that points to a structural problem
- Plumbing faults behind the sealant
If in doubt, ring 0345 464 0079 or email us and we will say what we think before booking.
Surfaces we seal
- Windows & doors
- Plot handovers
- Skirting & floors
- Bathrooms & en suites
- Show homes
- Kitchens
Looking after it afterwards
To keep the joints looking good and working properly:
- Do not wait for the house to settle if water is getting through
- Resist patching a failed seal with a tube from the DIY shop
- Wipe joints with warm soapy water
- Look at the sealant regularly in the first couple of years
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.
Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you.
Common questions in Wyck
Will you come out to Wyck?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Do you have insurance?
Yes. We are fully insured for domestic and commercial work.
Should I go to my builder first?
While the snagging or warranty period runs, the builder should be your first contact. If it is not sorted, or keeps failing, get in touch with us.
Do you use white or clear sealant?
Most bathroom joints are white or clear, but other colours are available. We match the colour to the finish before we begin.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Will the old sealant be removed?

Why deal with it now?
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times. Where a wall is exposed, as many are in small places like Wyck, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.
Why book with us
- Tidy, careful work
- Anti-fungal silicone where joints get wet
- Any old sealant cut out fully, not covered over
- Sealant colour chosen to suit
Surface by surface
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. We reseal them with a flexible sealant.
Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it in a colour to suit.
Common problems we fix in Wyck
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly and it shows once the home is in use.
Keep an eye out for these signs:
- Second-fix sealing on new plots
- Frame joints opening as the plaster dries
- Cracked caulk along new skirting
- Kitchen sealant that has pulled off the wall
Around Wyck, as everywhere, new build mastic is only as good as the preparation behind it.

What new build mastic looks like in Wyck
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.
