Trusted new build mastic in Leigh

Leigh: your questions answered

Will you come out to Leigh?

Yes, Leigh is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Is Leigh in your area for new build mastic?

Yes. Our work covers London and the South East, and Leigh is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.

Are you insured?

Yes. We are fully insured for every job we do.

Do you work for letting agents?

Yes. As well as householders, we work for landlords, agents, businesses and hotels across Kent.

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

It’s common, and there are usually two reasons: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.

I’m a tenant. Can you help?

We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.

Who should fix failed sealant in a new build?

If you are still within the builder’s snagging or warranty period, report it to them first. If they’re slow or the fix does not last, we can help.

Will there be a smell?

Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.

How we handle new build mastic in Leigh

Across Leigh, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method doesn’t change: remove, clean, prime where needed, then a neat new bead. If you have beads laid onto grit and dust from the build and gaps behind new kitchen upstands, we can help.

Somewhere as small as Leigh, 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.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

What happens on the day

When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before we start. The work normally takes a few hours in a single home. Somewhere like Leigh needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We go through the snagging list or plot schedule and agree the joints to do.
  2. We cut out every bit of the failed or messy sealant.
  3. Each joint is cleaned of dust and grit, then primed if required.
  4. A sealant chosen for each area goes in and is tooled smooth.
  5. Each area is checked and left with its cure time.

Getting ready for the visit

  • Clear items away from the joints we’re working on
  • Mention if the joints have been sealed before
  • Tell us if parking is tricky

Advice

How the job changes by surface

Plot handovers

Developers can send the plot schedule and specification and we’ll quote. We seal bathrooms, kitchens, frames and floors to the agreed spec.

Windows and doors

External mastic around new windows and doors is sometimes rushed or missed. It’s resealed with an exterior sealant suited to the frame and wall.

Landlord and commercial work in Leigh

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can go on one quote.

Housing providers, facilities teams and property managers book us too in Leigh and across Kent. We can quote a run of properties together, and we’re fully insured for the work.

Quotes for new build mastic in Leigh

We quote each job individually. These are the things that affect it:

  • The old material and how stubborn it is
  • Access and height
  • The product the joint needs
  • Any mould that needs treating

A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

What to tell us for a quote

Photos help, but a description is a good start. Try to tell us:

  • Roughly how big the job is
  • If someone has resealed it before
  • The problem you’ve noticed
  • The type of property

Every job is quoted individually. Simply call 0345 464 0079 or send us an email and describe the job.

What happens if it’s left?

DIY kits do not solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. Around Leigh, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.

What we’re called out for in Leigh

Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and the sealant may split.

Common reasons people contact us include:

  • Joints pulling apart as timber shrinks
  • Smeared, uneven beads picked up at snagging
  • Cracked caulk along new skirting
  • Shower seals failing in the first year or two

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

Before you book anyone

  • How much experience the applicator has
  • How long to leave it before use
  • Whether they’re fully insured
  • Which sealant they’ll use, and why

How to choose a mastic man

DIY sealant or a professional job?

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
