Wallington questions

Do you work for landlords with property near Fareham station?

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

Do you cover Wallington for new build mastic?

Yes. Our work covers London and the South East, and Wallington is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.

Do you work for hotels and businesses?

Yes. We’ve worked for hotels, offices and other businesses and we’re fully insured.

Why has my new-build shower seal failed already?

It’s common, and there are usually two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. Cutting it out and resealing properly fixes both.

Do you take on second-fix sealing for builders?

Is the work guaranteed?

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

Do you remove the old sealant?

Yes. All of the old material is cut out and the joint cleaned before resealing.

How do I get a quote for new build mastic in Wallington?

The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.

New build mastic in Wallington, done properly

If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. If you’re still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. Typical jobs include sealant applied over dusty or wet surfaces and plot mastic for developers ahead of handover, across windows & doors, show homes and skirting & floors.

Homes around Wallington range from older cottages to newer houses, and their floors range just as widely, from timber that moves with the seasons to tiles laid on concrete. Skirting and threshold joints need a sealant that suits the floor.

Each job carries a 12-month guarantee, whatever its size.

Honest limits

Some problems need a builder, plumber or other trade rather than us:

  • Cracking that points to a structural problem
  • Leaking fittings rather than failed sealant
  • A tray or bath that isn’t properly supported, until it’s fixed

Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.

What new build mastic looks like in Wallington

Wallington 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. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

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

DIY sealant or a professional job?

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

Work for landlords, hotels and businesses

Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.

If you manage several properties in or around Wallington, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs.

Do you need new build mastic in Wallington?

Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.

Any of these means the joints need attention:

  • Shower seals failing in the first year or two
  • Gaps behind new kitchen upstands
  • Joints pulling apart as timber shrinks
  • Cracked caulk along new skirting

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

Choosing a sealant specialist

How it works

A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. Most jobs take anything from a few hours to several days, depending on the number of plots. A visit to Wallington is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. Each joint is checked for movement before any work starts.
  2. We remove the failed sealant and clean the joints.
  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. The finished joints are checked and the cure times given.

Getting ready for the visit

  • Let us know if you’ve seen damp or leaks
  • Mention if the joints have been sealed before
  • Clear items away from the joints we are working on

Bathrooms and en suites

En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.

Kitchens

Sink joints are wet all the time. We use a sealant suited to kitchens suited to the job.

How we quote for new build mastic

For a quick quote, just ask. The main things that affect it are:

  • Mould in or behind the old joints
  • The size of the job
  • Any working-time requirements on site
  • The old material and how stubborn it is

No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

Asking for a quote

The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

  • What’s wrong with the joints now
  • Where the job is, and your postcode
  • If it’s domestic, commercial or a hotel
  • Any access issues, like height or stairs

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that is easy.
