New build mastic for Sawbridgeworth homes and businesses

New build mastic in Sawbridgeworth, done properly

If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first, and if it isn’t put right, get in touch with us. We work on kitchens, plot handovers and skirting & floors, and common reasons people get in touch are new-build shower sealant that has already split and cracked sealant around new window and door frames.

In smaller places like Sawbridgeworth, 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 our work is covered by a 12-month guarantee.

DIY versus a professional finish

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

What happens if it’s left?

It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote. In an older home around Sawbridgeworth, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.

No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

Why us?

  • Over 20 years’ experience
  • Tidy, careful work
  • Every job guaranteed for a year
  • Experience in homes, commercial sites and hotels

Aftercare tips

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

  • Watch for new gaps as the house dries out
  • Use the extractor fan every time you shower
  • Get a leaking seal dealt with straight away
  • Keep water off fresh sealant until it has cured

Keep photos of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.

Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.

What we do, step by step

When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most snagging lists, longer for a run of plots. For a job in Sawbridgeworth, we agree the time, the access and parking before the day. 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. Every bit of the old builder’s sealant is cut out down to clean surfaces.
  3. We clean out the dust and grit left from the build.
  4. Primer goes on where the surface and product need it, then the new sealant.
  5. Each bead is tooled and the cure times explained.

Before we arrive

  • On commercial sites, let us know about site rules
  • For indoor joints, keep the area dry beforehand if you can
  • Move anything stored near the joints

Show homes

Tired or marked sealant in a show home can be renewed. We cut it out and reseal neatly.

Kitchens

Worktop, upstand and sink joints in new kitchens often get a hurried bead. We take it out and reseal neatly, colour-matched where it shows.

What sealant work cannot fix

Sealant isn’t the answer to every problem, and we’ll tell you before any work starts. It won’t solve:

  • Deciding who is responsible under a builder’s warranty
  • Movement caused by a poorly fitted tray or bath
  • Broken tiles or a split tray

If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.

Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Yes, always. Each job is guaranteed for twelve months, large or small.

Can tenants book the work?

Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.

Can new sealant go on top of the old bead?

No. New silicone won’t bond to old silicone, so it soon lifts and traps water. We cut the old bead out completely.

Do you use white or clear sealant?

White and clear are the most common, but other colours are available. We match the colour to the finish.

Should I try DIY first?

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.

How much does new build mastic cost in Sawbridgeworth?

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
