How we quote for new build mastic

There’s no set price list, because no two jobs are the same. The quote depends on:

  • How many rooms, windows or areas are involved
  • Mould in or behind the old joints
  • Whether the work is at height
  • How much old sealant there is and how hard it is to remove

Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

What to tell us for a quote

Photos help, but a description is a good start. Please mention:

  • Whether it’s a home or a business
  • Where the property is
  • The problem you’ve noticed
  • Access, such as stairs, a lift or height

To get a quote, ring 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. You will have a clear quote before work begins.

New build mastic in Crooked Billet

Across Crooked Billet, 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: cut out, clean, prime where needed and reseal neatly. If you have second-fix sealing on new plots and gaps behind new kitchen upstands, we can put it right, whatever the surface.

London homes range from new-build flats to period conversions with new floors laid over old boards. Every joint between floor, skirting and threshold has to cope with some movement.

A one-year guarantee comes with the work, just as it does everywhere we cover.

Should I try it myself first?

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

A DIY attempt does not rule out a professional job. We remove it and do the joint properly.

Landlord and commercial work in Crooked Billet

Hotels need rooms back in use, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.

We also work for property managers and facilities teams in Crooked Billet and across Greater London. Several sites can be quoted together.

What sealant work can’t fix

A few problems are outside what sealant work can do:

  • Leaks from pipes, valves or wastes, which need a plumber
  • Cracked trays, tiles or worktops
  • Settlement cracks that need a surveyor

If you’re not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before you book.

Surfaces we seal

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

What we are called out for in Crooked Billet

Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Neither lasts long.

The most common problems we see are:

  • Sealant work across a run of new homes
  • Cracks appearing as a new home settles
  • Gaps between new skirting and floors
  • Frame joints opening as the plaster dries

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

Questions to ask before booking

  • What happens if they find a problem under the old sealant
  • Who turns up on the day
  • Is the old sealant removed completely?
  • How the colour is chosen

How to choose a mastic man

What we do, step by step

A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It normally takes a few hours in a single home. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Crooked Billet. It helps if you can point us to a visitor permit or a bay close to the door.

  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. Finally, each room is checked and you are given the cure time.

Before we arrive

  • For business premises, tell us about site rules or sign-in
  • Clear items away from the joints we are working on
  • Plan for the work area to be out of bounds to pets and children

Advice

FAQs for Crooked Billet

Can parking be tricky for a visit in Crooked Billet?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.

Can you help a landlord with a rental near Raynes Park station?

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’ll send you a clear quote.

Will the old sealant be removed?

Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.

Can you match the sealant colour to my new kitchen or bathroom?

It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before we start.

Do you guarantee your work?

Yes. All our work carries a 12-month guarantee.

How long will you be here?

That depends on how much there is to do, but most jobs take anything from a few hours to several days, depending on the number of plots. We’ll give you a better idea when we quote.

Why has my new-build shower seal failed already?

A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.

Will there be a smell?

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

Different surfaces, different methods

Skirting and floors

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

Windows and doors

On new builds, external frame sealant can be patchy. It’s resealed with an exterior sealant suited to the frame and wall.

New build mastic in Crooked Billet: local notes

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