How we handle new build mastic in Runfold

Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly rather than sitting on a layer of grit. Common call-outs are for shower seals failing in the first year or two and cracked sealant around new window and door frames, on show homes, windows & doors and plot handovers.

For a small place like Runfold, the journey and access are planned in advance, and once on site, the job is the same as anywhere.

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

Aftercare tips

Looking after new joints is easy:

  • Raise failed sealant with the developer while you’re covered
  • Look at the sealant regularly in the first couple of years
  • Follow the cure time we give you
  • Ventilate bathrooms well, especially in the first year

Avoid standing on the rim of the bath or the edge of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.

Early snagging is easier snagging. Left alone, a small crack can become a leak over time.

When to call us in Runfold

When the heating goes on in the first winter, the house dries fast. Gaps open along skirting, frames and worktops and cracked sealant shows up.

Signs it’s time to call us include:

  • Messy sealant that spoils new finishes
  • Internal frame sealant that has split
  • Beads laid onto grit and dust from the build
  • Joints pulling apart as timber shrinks

In and around Runfold, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Your questions about new build mastic in Runfold

Is Runfold within the area you cover?

Yes. Runfold is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you work for landlords with property near Farnham station?

Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.

Why has my new-build shower seal failed already?

Lots of new homes see sealant crack early. Poor preparation at handover adds to it.

Can you quote for more than one area?

Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.

What information do you need?

Tell us what needs doing and where, with photos by email if possible. We will ask anything else we need to know.

Should I go to my builder first?

Start with your builder while their snagging or warranty period runs. If that doesn’t work out, we are happy to quote and our work is guaranteed for a year.

Can I do it myself?

It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

What sealant do you use?

Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.

Honest limits

To be straight with you, some problems need a different trade:

  • Cracked trays, tiles or worktops
  • Leaking fittings rather than failed sealant
  • Cracking that points to a structural problem

If you are not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer.

Joints and surfaces we work on

  • Plot handovers
  • Skirting & floors
  • Show homes
  • Kitchens
  • Windows & doors
  • Bathrooms & en suites

The process

The work is kept neat and contained to the joints we are treating, so you can get on with your day. Expect the work to take a few hours for most snagging lists, longer for a run of plots, and we tell you how long to leave it before we go. In a small place like Runfold, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We start by going through the snagging items or plot schedule with you.
  2. The failed sealant is removed completely.
  3. We clean out the dust and grit left from the build.
  4. We prime where needed and apply a sealant suited to each joint.
  5. Each bead is tooled and the cure times explained.

Preparing for the visit

  • Try not to wet indoor joints just before the visit
  • Tell us about any water getting in
  • Tell us about any previous sealing or DIY attempts

Why act early in Runfold

For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time. Older cottages and farmhouses around Runfold can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or email us and we will give you an honest view and a quote.
