How we handle new build mastic in Staples Corner

For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. Typical jobs include second-fix sealing on new plots and messy sealant that spoils new finishes, across bathrooms & en suites, kitchens and windows & doors.

New flats are going up across London, many of them in larger developments. In a new development, snags are often reported through the developer or the managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.

Big or small, you get the same 12-month guarantee in Staples Corner and across Greater London.

How the job changes by surface

Skirting and floors

As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk.

Plot handovers

Developers can send the plot schedule and specification. Sealant work across the plot is covered.

How to look after the new joints

Looking after new joints is easy:

  • Wait for the cure time before using a resealed shower
  • Do not seal over failed sealant yourself
  • Watch for new gaps as the house dries out
  • Get a leaking seal dealt with right away

Avoid standing on the rim of the bath or the edge of the tray. Report any movement in a bath or tray.

The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left over time.

What affects the cost of new build mastic

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

  • The number and length of the joints
  • Any working-time requirements on site
  • How many areas need sealing
  • The product the joint needs

What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

Asking for a quote

When you call or email, it’s useful to know:

  • The type of property
  • What the problem is, such as mould, gaps, leaks or cracking
  • Roughly how big the job is
  • Where the property is

Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. When it suits you, phone 0345 464 0079 or send us an email.

Can I do it myself?

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.

New homes and floors in Staples Corner

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. Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent.

How the visit works

We bring everything the job needs with us. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours for most snagging lists, longer for a run of plots. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.

  1. First, the list of joints is agreed from your snagging sheet or plot schedule.
  2. The failed sealant is removed completely, with no layer left behind.
  3. We clean out the dust and grit left from the build.
  4. Primer goes on where the surface and product need it, then the new sealant.
  5. Each bead is tooled and the cure times explained.

How to prepare

  • Tell us about any water getting in
  • Let us know about earlier repairs to the joints
  • Clear items away from the joints we’re working on

Advice

Common problems we fix in Staples Corner

The first winter with the heating on dries a new home quickly. Gaps open along skirting, frames and worktops.

  • Worktop and upstand sealant coming away
  • New-build shower sealant that has already split
  • Untidy sealant flagged on a snagging list

Staples Corner questions

I let a flat near Brent Cross West station. Can you help?

Yes, we work for letting agents and landlords. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.

Can you do new build mastic in Staples Corner?

Yes. Our work covers London and the South East, and Staples Corner is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing, and we will 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, and we will explain our choice.

Are you insured?

Yes. Full insurance covers our work, and we can confirm the details when we quote.

Is the work guaranteed?

Yes: twelve months. If anything isn’t right with the work within the year, let us know and we will sort it.

Is it worth resealing while the house is still settling?

If the seal has failed and water is getting in, do it now. Hairline cosmetic gaps can wait until the house has settled.

Is it messy?

Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.

How long will you be here?

As a guide, most jobs take a few hours in a single home. Bigger jobs take longer.
