How we handle new build mastic in Richmond

A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. Common call-outs are for sealant that never bonded to the surface and joints pulling apart as timber shrinks, across windows & doors, bathrooms & en suites and kitchens.

Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, while new homes need a neat, sound finish around frames, baths and kitchens before handover, in Richmond and beyond.

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

Looking after it afterwards

How long the joints last depends on use and care. Here’s what we suggest:

  • Act quickly if a seal starts to leak
  • Record problems with dated pictures
  • Raise failed sealant with the developer while you are covered
  • Follow the cure time we give you

Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.

The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak over time.

Surface by surface

Plot handovers

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

Windows and doors

Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant that suits the frame.

Work for landlords, hotels and businesses

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.

Housing providers, facilities teams and property managers book us too. Several sites can go on one quote.

FAQs for Richmond

Can you help a landlord with a rental near Richmond station?

Yes, we work for landlords and agents. Just call 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.

Is Richmond in your area for new build mastic?

Yes, Richmond is within the area we cover. Our work covers London and the South East. 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 quote.

What colour sealant will you use?

It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We will agree it with you first.

Can you work on commercial sites?

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

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

A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Either can make it fail early.

When is the sealant fully cured?

Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used before we leave.

How long does the job take?

As a guide, most jobs take anything from a few hours to several days, depending on the number of plots. Larger jobs naturally take longer, and we’ll tell you how long to expect.

Can you work from my snagging list?

Yes. We often work straight from a snagging list. We’ll go through the sealant items and agree what we’ll do.

Quotes for new build mastic in Richmond

We do not publish a price list, because jobs vary so much. The quote depends on:

  • Any working-time requirements on site
  • How much old sealant there is and how hard it is to remove
  • Whether the work is at height
  • The type of sealant required

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

To help us quote quickly, please include:

  • The rough size of the job
  • What the problem is, such as mould, gaps, leaks or cracking
  • Whether it’s a home or a business
  • Photos by email, if that is easy

Every job is quoted individually, so start by telling us what you need. Simply ring 0345 464 0079 or drop us an email and describe the job and send photos if you have them.

New build mastic around Richmond

The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent.

For new homes near Richmond station, it’s worth checking the sealant early, while snags are still fresh. Richmond is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Leave it or put it right?

A tube of sealant from the DIY shop will not fix the cause: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.

Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will go through it with you.

What you get with us

  • Anti-fungal silicone where joints get wet
  • We agree the colour with you first
  • Experience in homes, commercial sites and hotels
  • 20+ years of sealant experience

Honest limits

It helps to know what we cannot do too:

  • Leaks from pipes, valves or wastes, which need a plumber
  • Cracked trays, tiles or worktops
  • Disputes or warranty claims with your builder

If you are not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.

Joints and surfaces we work on

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

What we do, step by step

There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the job takes a few hours for most snagging lists, longer for a run of plots for a typical job. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents 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.
  3. We clean out the dust and grit left from the build.
  4. We prime where needed and apply a sealant suited to each joint.
  5. Each bead is tooled and the cure times explained.

Before we arrive

  • On commercial sites, let us know about site rules
  • Let us know about stairs, lifts or work at height
  • Keep children and pets away from the work area
