New build mastic in Twydall, done properly

Snagging sealant properly means taking the failed bead out completely. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. We work on kitchens, show homes and plot handovers, and people most often call us about gaps opening as the house dries out and settles and sealant that never bonded to the surface.

In smaller places like Twydall, 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.

You get a one-year guarantee, the same in Twydall as everywhere else we work.

What affects the cost of new build mastic

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

  • Which sealant suits the joint
  • When we can work, for business premises
  • Whether old sealant or filler has to be cut out
  • How much there is to do

Leaving a failed joint normally makes the job bigger, not smaller. If you’re unsure, call 0345 464 0079 or email us for an honest opinion and a quote.

Helping us quote

To make quoting easier, please include:

  • The problem you’ve noticed
  • If someone has resealed it before
  • If it’s domestic, commercial or a hotel
  • Roughly how big the job is

For new build mastic in Twydall, phone 0345 464 0079 or drop us an email. Tell us what the problem is and where, and we will agree the price before any work begins.

How it works

At the end, we look at the finished work together and tell you how long to leave it. The visit itself normally takes a few hours for most snagging lists, longer for a run of plots, depending on the size of the job. For a job in Twydall, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. We start by going through the snagging items or plot schedule with you.
  2. Every bit of the old builder’s sealant is cut out.
  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. We tool every joint neatly and tell you when each area can be used.

Getting ready for the visit

  • Mention any parking rules near the property
  • Move anything stored near the joints
  • Let us know about stairs, lifts or work at height

Can I do it myself?

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Keeping the joints in good condition

Looking after new joints is easy:

  • Act quickly if a seal starts to leak
  • Avoid scourers and strong chemicals on sealant
  • Open a window or run the fan after bathing
  • Avoid running a DIY bead over the old one

Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents, which can damage the surface.

Report failed sealant to the builder while you are in the snagging period. Once it ends, the repair may be down to you.

Why act early in Twydall

Running a new bead over the builder’s sealant might look tidy for a few weeks, but it can’t bond to what’s underneath. A lasting seal starts with removing the old one completely. Homes in smaller places like Twydall can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.

The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.

Why book with us

  • Sanitary silicone with an anti-fungal additive in wet areas
  • Any old sealant cut out fully, not covered over

Do you have insurance?

Yes, we are fully insured.

Why does sealant fail so quickly in new builds?

It’s common, and there are normally two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. Cutting it out and resealing properly fixes both.

Do you work for developers?

Yes. Plot mastic and second-fix sealing for developers is part of our work. Send us the plot schedule and we will quote.

When is the sealant fully cured?

Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.

What do you need from me for a quote?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

Can you match the sealant colour to my new kitchen or bathroom?

White and clear are the most common, but other colours are available. We choose one to suit the room before we begin.
