About our new build mastic in West Marden
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. If you have sealant that never bonded to the surface and smeared, uneven beads picked up at snagging, we can help.
Somewhere as small as West Marden, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

How we quote for new build mastic
Jobs vary more than people expect. What affects the quote:
- Whether there’s mould to deal with
- How much old sealant there is and how hard it is to remove
- The type of sealant required
- Access and height
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Asking for a quote
Before you ask for a quote, have a think about:
- If it’s domestic, commercial or a hotel
- Access, such as stairs, a lift or height
- How many joints, rooms or windows are involved
- Photos by email, if that’s easy
There’s no standard price list, because every job is different. Instead, we send you a clear quote for your job. To get started, phone 0345 464 0079 or send us an email.
What the job involves on each surface
Windows and doors
On new builds, external frame sealant can be patchy. We reseal it with a weatherproof, flexible sealant.
Skirting and floors
Wet-area floor joints need a flexible seal. They get a flexible, water-resistant sealant.
How it works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most snagging lists, longer for a run of plots, and the area is left clean. Somewhere like West Marden needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Clear the area around the work
- Tell us about any water getting in

Advice
Why deal with it now?
A quick bead over the top of the old sealant can look fine at first, but it can’t bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. Where a wall is exposed, as many are in small places like West Marden, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, phone 0345 464 0079 or send us an email for an honest opinion and a quote.
