Signs you need new build mastic in Earlstone Common

New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open.

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

  • Sealant applied over dusty or wet surfaces
  • Plot mastic for developers ahead of handover
  • Messy sealant that spoils new finishes
  • Gaps opening as the house dries out and settles

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

Questions to ask before booking

  • How much experience the applicator has
  • What the cure time is
  • What insurance they hold
  • What guarantee comes with the work

Choosing a sealant specialist

New build mastic in Earlstone Common, done properly

Across Earlstone Common, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: cut out, clean, prime where needed and reseal neatly. Typical jobs include shower seals failing in the first year or two and gaps behind new kitchen upstands, on windows & doors, show homes and plot handovers.

Somewhere as small as Earlstone Common, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

What the job involves on each surface

Bathrooms and en suites

New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.

Kitchens

Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.

Why it’s worth doing now in Earlstone Common

If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or is not dealt with, we can reseal it properly. In a small place like Earlstone Common, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

How the visit works

We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most snagging lists, longer for a run of plots. In a small place like Earlstone Common, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We look at why each joint failed, including any movement.
  2. Old sealant is cut out and the joints cleaned.
  3. Joints are dried and primed where the product calls for it.
  4. New sealant goes in, with baths filled first so they’re at their heaviest.
  5. The finished joints are checked and the cure times given.

How to prepare

  • Keep pets and children clear of the area while we work
  • Clear the area around the work
  • Try not to wet indoor joints just before the visit

Looking after it afterwards

Looking after new joints is easy:

  • Raise failed sealant with the developer while you’re covered
  • Photograph failed sealant before it’s redone
  • Ventilate bathrooms well, especially in the first year
  • Do not wait for the house to settle if water is getting through

Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.

Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and protects the rest of the house.

Does someone need to be in?

If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.

We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we are using.
