Trusted new build mastic in Bowcombe

How the visit works

Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for most snagging lists, longer for a run of plots. For a village or hamlet like Bowcombe, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  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. Baths are filled with water, then the new sealant is applied.
  5. We check every joint and leave you with the cure times.

Before we arrive

  • Try not to wet indoor joints just before the visit
  • Mention if the joints have been sealed before
  • Keep pets and children clear of the area while we work

About our new build mastic in Bowcombe

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 with a sealant suited to each area. If you have beads laid onto grit and dust from the build and gaps behind new kitchen upstands, we can put it right, whatever the surface.

In a village or hamlet like Bowcombe, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.

All our work is covered by a 12-month guarantee.

How we quote for new build mastic

We quote each job individually. These are the things that affect it:

  • The product the joint needs
  • How many rooms, windows or areas are involved
  • Whether there’s mould to deal with
  • How much old sealant there is and how hard it is to remove

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

What to tell us for a quote

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • The problem you’ve noticed
  • Pictures of the joints, sent by email
  • Any access issues, like height or stairs
  • The address or postcode of the job

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.

Looking after it afterwards

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

  • Raise failed sealant with the developer while you are covered
  • Resist patching a failed seal with a tube from the DIY shop
  • Act quickly if a seal starts to leak
  • Check bath and shower seals every few months as the house settles

Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.

Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in saves a harder job later.

Should I try it myself first?

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Why act early in Bowcombe

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. Where a wall is exposed, as many are in small places like Bowcombe, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.

Bathrooms and en suites

En suite showers are a common source of leaks into the room below. A proper reseal keeps water in the tray.

Show homes

Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish ready for viewings. Tell us when the home is open so we can plan around it.

Landlord and commercial work in Bowcombe

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
