What we can’t put right

We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:

  • Cracked trays, tiles or worktops
  • Cracking that points to a structural problem
  • Movement caused by a poorly fitted tray or bath

Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before booking.

How we handle new build mastic in Merle Common

Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. Both get the same care over preparation. If you have frame joints opening as the plaster dries and beads laid onto grit and dust from the build, we can put it right, on plot handovers, skirting & floors and kitchens alike.

Older homes in small places like Merle Common often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.

Our work is backed for twelve months, and the guarantee is the same wherever you are.

Keeping the joints in good condition

Once the sealant has cured, a few habits help it last:

  • Put sealant faults on your snagging list early
  • Avoid scourers and strong chemicals on sealant
  • Check bath and shower seals every few months as the house settles
  • Use the extractor fan every time you shower

Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry.

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 in a busy bathroom.

How the job changes by surface

Skirting and floors

Wet-area floor joints need a flexible seal. We seal them with a sealant suited to wet areas.

Windows and doors

The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant.

What happens if it’s left?

Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. In a small place like Merle Common, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Why us?

  • We’re fully insured
  • 12-month guarantee on every job
  • We leave the area clean and tidy
  • Quality sealants from Arbo and Everbuild

The process

At the end, we look at the finished work together. The visit itself usually takes anything from a few hours to several days, depending on the number of plots, depending on the size of the job. Somewhere like Merle Common needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
  2. We cut out every bit of the failed or messy sealant.
  3. We clean off dust from the build and prime the surfaces where the product needs it.
  4. New sealant suited to each joint is applied and tooled neatly.
  5. Each area is checked and left with its cure time.

Before we arrive

  • Keep pets and children clear of the area while we work
  • Mention any sign-in or site rules at work premises
  • Let us know about parking restrictions

Advice

Quotes for new build mastic in Merle Common

Some jobs are bigger than they look, and some smaller. What affects the quote:

DIY sealant or a professional job?

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
