New build mastic for homes and businesses in Grange

Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. Both get the same care over preparation since hurried prep is behind a lot of new-build failures. We work on plot handovers, windows & doors and bathrooms & en suites, and people most often call us about second-fix sealing on new plots and leaking shower tray seals in a new home.

Somewhere as small as Grange, 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’ll sort it.

Signs you need new build mastic in Grange

If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes do not always leave time for joints to dry before the sealant goes on.

Common reasons people contact us are:

  • Gaps between new skirting and floors
  • Shower seals failing in the first year or two
  • Frame joints opening as the plaster dries
  • Worktop and upstand sealant coming away

Around Grange, as everywhere, new build mastic is only as good as the preparation behind it.

New build mastic in Grange: local notes

Grange is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

For new homes near Gillingham (Kent) station, it’s worth checking the sealant early, while snags are still fresh.

Your questions about new build mastic in Grange

Will you come out to Grange?

Yes. Grange is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Can you help a landlord with a rental near Gillingham (Kent) station?

Yes. We work for landlords and letting agents as well as householders, and several properties can go on one quote. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.

Do you work for hotels and businesses?

Yes. We have worked for hotels, offices and other businesses, and we are fully insured.

Can new sealant go on top of the old bead?

No. Fresh silicone doesn’t stick to the old layer, so it soon lifts and traps water. The old sealant always comes out first.

Should I wait before resealing?

If the seal has failed and water is getting in, do it now. Small gaps that are just cosmetic can be resealed once movement has slowed.

What sealant do you use?

We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.

Is there a guarantee?

Yes, always. Each job is guaranteed for twelve months.

Can I send you my snagging list?

Yes. Snagging lists are a common starting point for us. We’ll go through the sealant items and agree what we’ll do.

Different surfaces, different methods

Bathrooms and en suites

Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in and baths are filled before sealing.

Plot handovers

Send us the schedule and any sealant specification for a quote. We seal bathrooms, kitchens, frames and floors.

Quotes for new build mastic in Grange

Jobs vary more than people expect. What affects the quote:

  • Access and height
  • Any mould that needs treating
  • The product the joint needs
  • Any working-time requirements on site

Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will go through it with you.

What we need to know

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • What’s wrong with the joints now
  • A few pictures by email, if you can
  • If it’s domestic, commercial or a hotel
  • How many joints, rooms or windows are involved

It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. When it suits you, phone 0345 464 0079 or drop us an email.

What sealant work can’t fix

Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:

  • Disputes or warranty claims with your builder
  • Movement caused by a poorly fitted tray or bath
  • Cracked trays, tiles or worktops

Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.

Surfaces we seal

  • Show homes
  • Plot handovers
  • Windows & doors
  • Skirting & floors
  • Kitchens
  • Bathrooms & en suites

The process

Every visit runs the same way: we check the joints, protect the area around them, do the work and tidy away. Most jobs take a few hours in a single home. Somewhere like Grange needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. We look at why each joint failed, including any movement.
  2. Old sealant is cut out and the joints cleaned.
  3. Joints are dried and primed where the product calls for it.
  4. Baths are filled with water, then the new sealant is applied.
  5. The finished joints are checked and the cure times given.

Getting ready for the visit

  • Plan for the work area to be out of bounds to pets and children
  • Let us know if you’ve seen damp or leaks
  • Mention any sign-in or site rules at work premises

Advice

Why deal with it now?

Small cosmetic gaps can wait for the house to settle, but water getting through can’t. Not sure whether yours can wait? You can ring 0345 464 0079 or email us with a few photos. Older cottages and farmhouses around Grange can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
