Typical jobs include kitchen sealant that has pulled off the wall and second-fix sealing on new plots, on kitchens, bathrooms & en suites and show homes.

What the job involves on each surface

Plot handovers

Developers can send the plot schedule and specification for a quote. Sealant work across the plot is covered as agreed.

Windows and doors

Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.

Leave it or put it right?

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. Older cottages and farmhouses around Mayfield can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.

How we quote for new build mastic

We do not publish a price list. What we look at:

  • When we can work, for business premises
  • The old material and how stubborn it is
  • How many areas need sealing
  • Whether there’s mould to deal with

Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

Asking for a quote

There’s no need for technical detail. It helps if you can tell us:

  • Roughly how big the job is
  • Photos by email, if that’s easy
  • The address or postcode of the job

How the visit works

We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. The job normally takes anything from a few hours to several days, depending on the number of plots, and we tell you how long to leave it before we go. Somewhere like Mayfield needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We look at why each joint failed, including any movement.
  2. We remove the failed sealant and clean the joints.
  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. We check every joint and leave you with the cure times.

  • Keep pets and children clear of the area while we work
  • Mention any parking rules near the property
  • Tell us about any previous sealing or DIY attempts

Landlord and commercial work in Mayfield

Failed sealant is one of the commonest items on a check-out report. Several properties can be quoted together.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.

Keeping the joints in good condition

After the cure time, these simple habits help:

  • Keep water off fresh sealant until it has cured
  • Keep photos and emails about snagging items
  • Clean sealant with mild detergent, not abrasives
  • Check bath and shower seals every few months as the house settles

Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers so moisture does not sit on the sealant.

Lifting sealant traps moisture and mould behind it. Resealing before mould gets in saves a harder job later.

Can I do it myself?

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
