New build mastic in Tooting

Can I do it myself?

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

How we handle new build mastic in Tooting

Across Tooting, we work for both new-home owners and the builders handing those homes over. Whether it’s one en suite or a run of plots, the method is the same: remove, clean, prime where needed, then a neat new bead. Common call-outs are for beads laid onto grit and dust from the build and cracked sealant around new window and door frames, on skirting & floors, bathrooms & en suites and show homes.

London homes range from new-build flats to period conversions with new floors laid over old boards. Wherever a floor meets a wall, a skirting or a threshold, the joint has to allow for movement.

Our work is backed for twelve months, in Tooting and everywhere else we cover.

Common questions in Tooting

I let a flat near Tooting station. Can you help?

Yes, rental work is part of what we do. Just call 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.

Do you cover Tooting for new build mastic?

Yes. Our work covers London and the South East, and Tooting is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear price.

Which products 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.

Do I have to be there?

If the work is inside, we need someone to let us in. After that, you can carry on with your day.

Do you have insurance?

Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.

Do you work for hotels and businesses?

Yes. Hotels, offices and other businesses use us, and we are fully insured.

Will you leave a mess?

Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.

Should I wait before resealing?

It depends on whether water is getting through. A leaking shower or bath seal should be redone straight away, while small cosmetic gaps can wait a while.

What we are called out for in Tooting

If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints are not always given time to dry before the sealant goes on.

Look out for any of the following:

  • Frame joints opening as the plaster dries
  • Shower seals failing in the first year or two
  • Cracked caulk along new skirting
  • Second-fix sealing on new plots

Tooting is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Before you book anyone

  • Is the old sealant removed completely?
  • What the quote includes, VAT included or not
  • How long to leave it before use
  • What insurance they hold

Our hiring checklist

Keeping the joints in good condition

How long the joints last depends on use and care. We suggest:

  • Watch for new gaps as the house dries out
  • Avoid scourers and strong chemicals on sealant
  • Keep pictures and emails about snagging items
  • Get a leaking seal dealt with straight away

Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day to cure enough for use.

A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.

Different surfaces, different methods

Plot handovers

We work through plots to your schedule, sealing each room ready for handover. Each joint is cleaned and primed where needed to keep callbacks down.

Skirting and floors

Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it.

New build mastic in Tooting: local notes

Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

If you’ve bought a new home near Tooting station, the sealant around baths, showers and frames is worth checking in the first year or two.

Work for landlords, hotels and businesses

We also work for property managers and facilities teams in Tooting and across Greater London. Several sites can go on one quote, and we are fully insured for the work.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.

What we can’t put right

New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:

  • Disputes or warranty claims with your builder
  • Settlement cracks that need a surveyor
  • Leaks from pipes, valves or wastes, which need a plumber

If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before booking.

What we seal

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

How it works

There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes anything from a few hours to several days, depending on the number of plots in most cases. In a London area like Tooting, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.

  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. 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.

Before we arrive

  • Tell us about access, such as stairs, a lift or high-level joints
  • Mention any parking rules near the property
  • Clear items away from the joints we’re working on
