Trusted new build mastic in Maze Hill

New build mastic for homes and businesses in Maze Hill

Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first and if that stalls, we can do it. If you are dealing with cracked sealant around new window and door frames and shower seals failing in the first year or two, we can help, whatever the surface.

Across London, commercial floors have movement joints that break down under heavy foot traffic, while new homes need a neat, sound finish around frames, baths and kitchens before handover.

We stand behind the work with a one-year guarantee, so you are covered after we’ve gone.

Signs you need new build mastic in Maze Hill

Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly.

If you can see any of these, it’s time to have the joints looked at:

  • Sealant that never bonded to the surface
  • New-build shower sealant that has already split
  • Smeared, uneven beads picked up at snagging
  • Cracks appearing as a new home settles

As a London address, Maze Hill can be tricky for parking: let us know about parking bays, permits or a driveway.

Questions to ask before you book

  • How the colour is chosen
  • The length of the guarantee
  • What the cure time is
  • Is VAT in the price?

New build mastic around Maze Hill

Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent.

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

There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.

Are you fully insured?

Yes. Mr Mastic is fully insured.

My new home is still under warranty. Should I contact you?

Your builder, if you’re still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it and our work is guaranteed for a year.

Can I send you my snagging list?

Yes. Send it with pictures and we will quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.

We work from Crawley. Our applicators cover Maze Hill, along with the rest of our area.

Yes. All our work carries our one-year guarantee.

Honest limits

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

  • Your warranty claim itself, which is between you and the builder
  • Settlement cracks that need a surveyor
  • Leaks from pipes, valves or wastes, which need a plumber

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

The process

Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a few hours for most snagging lists, longer for a run of plots, depending on the amount of work. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Maze Hill. A visitor permit or a nearby bay makes the visit run more smoothly.

  1. We go through the snagging list or plot schedule and agree the joints to do.
  2. The old bead comes out in full, with no layer left behind.
  3. We clean off dust from the build and prime the surfaces where the product needs it.
  4. We apply a sealant that suits each joint and tool it to a neat finish.
  5. We check every joint and tell you how long each needs to cure.

Preparing for the visit

  • Let us know about earlier repairs to the joints
  • Tell us if parking is tricky
  • Mention any leaks or damp you’ve noticed

How we quote for new build mastic

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

  • The type of sealant required
  • Any working-time requirements on site
  • Whether the work is at height
  • The old material and how stubborn it is

A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

What to tell us for a quote

To help us quote quickly, please include:

  • Photos by email, if that is easy
  • Whether it has been sealed before
  • Access, such as stairs, a lift or height
  • Where the property is

It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. Whenever you’re ready, ring 0345 464 0079 or drop us an email.

Surface by surface

Kitchens

Sink joints are wet all the time. A kitchen sealant goes in there suited to the job.

Bathrooms and en suites

Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.

Keeping the joints in good condition

So the new joints stay in good condition:

  • Clean sealant with mild detergent, not abrasives
  • Put sealant faults on your snagging list early
  • Open a window or run the fan after bathing
  • Wait for the cure time before using a resealed shower

Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing so moisture doesn’t sit on the sealant.

Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in keeps the job straightforward.
