Why act early in Marehill

New build mastic in Marehill
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. We work on skirting & floors, windows & doors and bathrooms & en suites, and common reasons people get in touch are messy sealant that spoils new finishes and plot mastic for developers ahead of handover.
Work in a small place like Marehill just needs the journey and access planning, and once on site, the job is the same as anywhere.
A one-year guarantee comes as standard.

Different surfaces, different methods
Plot handovers
Plot mastic is carried out to the developer’s schedule. Each joint is cleaned and primed where needed to keep callbacks down.
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant that suits the frame.

What affects the quote in Marehill
There’s no set price list, because jobs vary so much. What we look at:
- Any working-time requirements on site
- The number of rooms or windows
- The type of sealant required
- How much old sealant there is and how hard it is to remove
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.
What we need to know
When you call or email, it’s useful to know:
- The address or postcode of the job
- The problem you’ve noticed
- Any previous sealing or DIY work
- How many joints, rooms or windows are involved
Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand, and we will come back to you with a quote.
What we cannot put right
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Leaks from pipes, valves or wastes, which need a plumber
- Broken tiles or a split tray
- Movement caused by a poorly fitted tray or bath
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.

What we do, step by step
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours for most snagging lists, longer for a run of plots. For a village or hamlet like Marehill, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- 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
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can
- Keep pets and children clear of the area while we work

Joints and finishes in Marehill homes
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For new homes near Pulborough station, it’s worth checking the sealant early, while snags are still fresh. Around Marehill, as everywhere, new build mastic is only as good as the preparation behind it.

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Act quickly if a seal starts to leak
- Put sealant faults on your snagging list early
- Ventilate bathrooms well, especially in the first year
- Record problems with dated pictures
Follow the cure time we give you before the area gets wet. Most silicones need around a day before water reaches them.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small.
