New build mastic in Mowshurst

About our new build mastic in Mowshurst

Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks instead of bonding to the dust. If you have leaking shower tray seals in a new home and cracks appearing as a new home settles, we can help, on skirting & floors, windows & doors and kitchens alike.

In a village or hamlet like Mowshurst, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.

Our work is backed for twelve months.

How we quote for new build mastic

We quote each job individually. This is what makes a difference:

  • Access and height
  • The type of sealant required
  • When we can work, for business premises
  • Whether old sealant or filler has to be cut 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. Ask us for a quote and we will explain what it covers.

Asking for a quote

There’s no need for technical detail. Just tell us:

  • Whether it has been sealed before
  • The type of property
  • What’s wrong with the joints now
  • How we’d reach the joints

For a quote, phone 0345 464 0079 or send us an email with the location and a short description of the problem. We’ll give you a clear price before any work starts.

What happens on the day

We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on the number of plots and we leave things clean and tidy. In a small place like Mowshurst, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We start by going through the snagging items or plot schedule with you.
  2. Every bit of the old builder’s sealant is cut out, with no layer left behind.
  3. We clean out the dust and grit left from the build.
  4. Primer goes on where the surface and product need it, then the new sealant.
  5. Each bead is tooled and the cure times explained.

How to prepare

  • On commercial sites, let us know about site rules
  • Move anything stored near the joints
  • Mention any tricky access

Common questions in Mowshurst

Do you work for landlords with property near Edenbridge station?

Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.

Will you come out to Mowshurst?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Is there a guarantee?

Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.

Is it normal for sealant to crack in a new home?

New homes dry out and move in their first couple of years, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.

How much does new build mastic cost in Mowshurst?

Size, access and the old material all affect the cost. Ask us for a quote.

What information do you need?

A short description and the location, with pictures by email if possible. We’ll ask anything else we need to know.

What colour sealant will you use?

It depends on the joint: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before work begins.

Can I send you my snagging list?

Yes. We often work straight from a snagging list. We will go through the sealant items and agree what we’ll do.

Leave it or put it right?

It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote. Where a wall is exposed, as many are in small places like Mowshurst, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

What you get with us

  • Tidy, careful work
  • Colour agreed with you before any work starts
  • Over 20 years’ experience
  • 4.9 on Google from 180+ five-star reviews

See our cost guide or customer reviews.

Should I try it myself first?

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

For landlords and businesses

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

What we are called out for in Mowshurst

If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints aren’t always given time to dry.

Most people get in touch after spotting something like this:

  • Messy sealant that spoils new finishes
  • Worktop and upstand sealant coming away
  • Leaking shower tray seals in a new home
  • Gaps opening as the house dries out and settles

In and around Mowshurst, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Before you book anyone

  • Whether VAT is included
  • How much experience the applicator has
  • When the joint can take water or movement
  • What product goes in the joint
