Work for landlords, hotels and businesses

Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

New build mastic in Great Hollands

A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. If you have beads laid onto grit and dust from the build and sealant work across a run of new homes, we can help, on kitchens, plot handovers and show homes alike.

In smaller places like Great Hollands, new homes tend to come as small developments or single plots. The sealant around baths, showers, frames and skirtings needs to be right from the start.

All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Quotes for new build mastic in Great Hollands

Jobs vary more than people expect. What affects the quote:

  • Any mould that needs treating
  • The product the joint needs
  • The number of rooms or windows
  • Whether the work is at height

Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.

What we need to know

Photos by email are helpful but not essential. Try to tell us:

  • Photos by email, if that’s easy
  • What the problem is, such as mould, gaps, leaks or cracking
  • Roughly how big the job is
  • How we’d reach the joints

Every job is quoted individually. Just ring 0345 464 0079 or send us an email with the details and send pictures if you have them.

The process

Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours in a single home. A visit to Great Hollands is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. First, the list of joints is agreed from your snagging sheet or plot schedule.
  2. The failed sealant is removed completely.
  3. Joints are vacuumed and cleaned of building dust.
  4. We prime where needed and apply a sealant suited to each joint.
  5. Each bead is tooled and the cure times explained.

How to prepare

  • Let us know about earlier repairs to the joints
  • Let us know about parking restrictions
  • Tell us about access, such as stairs, a lift or high-level joints

Do you take on second-fix sealing for builders?

Can you do several jobs on one visit?

Yes. More than one area can go on one quote.

Will there be a smell?

Some sealants have a smell while they cure, but it fades. Ventilation helps.

What does new build mastic cost?

Size, access and the old material all affect the cost. Call for a quick quote.

Why does sealant fail so quickly in new builds?

New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.

Can you work from my snagging list?

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

Aftercare tips

How long the joints last depends on use and care. We suggest:

  • Avoid scourers and strong chemicals on sealant
  • Watch for new gaps as the house dries out
  • Follow the cure time we give you
  • Put sealant faults on your snagging list early

Keep pictures of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.

If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.

Surface by surface

Skirting and floors

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

Bathrooms and en suites

En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.

Should I try it myself first?

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
