How the visit works

Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours in a single home. For a village or hamlet like Fields End, the journey is planned in advance: 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.

  1. Each joint is checked for movement before we start.
  2. Old sealant is cut out and the joints cleaned.
  3. Joints are dried and primed where the product calls for it.
  4. New sealant goes in, with baths filled first so they’re at their heaviest.
  5. We check every joint and leave you with the cure times.

How to prepare

  • Tell us about access, such as stairs, a lift or high-level joints
  • Let us know about earlier repairs to the joints
  • Tell us if parking is tricky

Advice

New build mastic for homes and businesses in Fields End

Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks instead of bonding to the dust. Common call-outs are for cracked sealant around new window and door frames and gaps between new skirting and floors, on skirting & floors, kitchens and show homes.

In a village or hamlet like Fields End, new homes are more likely to be a barn conversion or a handful of houses than a big 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 something isn’t right with it in that time, tell us and we will put it right.

Different surfaces, different methods

Plot handovers

Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing.

Bathrooms and en suites

Trays and baths in new builds settle as they’re used. The joint is stripped back before the new bead goes in with baths filled first.

Looking after it afterwards

Looking after new joints is easy:

  • Check bath and shower seals every few months as the house settles
  • Avoid running a DIY bead over the old one
  • Wipe joints with warm soapy water
  • Keep water off fresh sealant until it has cured

Watch the joints as the house settles. Small gaps can appear as the house dries.

If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.

What we cannot put right

We will always be straight with you, so here’s what new sealant will not do:

  • Cracking that points to a structural problem
  • Disputes or warranty claims with your builder
  • A tray or bath that isn’t properly supported, until it’s fixed

If you are not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer.

What we seal

  • Windows & doors
