New build mastic in Heathrow
Across Heathrow, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: cut out, clean, prime where needed and reseal neatly. Common call-outs are for new-build shower sealant that has already split and second-fix sealing on new plots, on kitchens, plot handovers and skirting & floors.
Somewhere as small as Heathrow, 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.
Your job is guaranteed for a year, as with all our work.

Honest limits
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Your warranty claim itself, which is between you and the builder
- Leaking fittings rather than failed sealant
- A tray or bath that isn’t properly supported, until it’s fixed
If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.

Surface by surface
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish to a tidy standard. We’ll plan around viewing times.
Skirting and floors
New homes often develop a gap between skirting and floor. We seal it with a flexible sealant that copes with the movement.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.

Before you ask for a quote, have a think about:
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

The process
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes anything from a few hours to several days, depending on the number of plots from start to finish. Somewhere like Heathrow needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park.

- We go through the snagging list or plot schedule and agree the joints to do.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Clear items away from the joints we are working on
- Mention any leaks or damp you’ve noticed

Advice
How to look after the new joints
Looking after new joints is easy:
- Look at the sealant regularly in the first couple of years
- Follow the cure time we give you
- Ventilate bathrooms well, especially in the first year
- Wipe joints with warm soapy water
Follow the cure time we give you before the area gets wet. Silicone is usually left for about a day.
Early snagging is easier snagging. Small faults turn into leaks if left in a busy bathroom.
