Trusted new build mastic in Penpont

When it isn’t the sealant

We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:

  • Cracked trays, tiles or worktops
  • Your warranty claim itself, which is between you and the builder
  • Leaking fittings rather than failed sealant

If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think before booking.

Joints and surfaces we work on

  • Windows & doors

  • Skirting & floors

How we handle new build mastic in Penpont

A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. We’re often asked to deal with frame joints opening as the plaster dries and gaps between new skirting and floors, across windows & doors, show homes and bathrooms & en suites.

Around smaller Scottish places like Penpont, new homes tend to be single plots or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.

Our work is backed for twelve months, and the guarantee is the same wherever you are.

Will it make a mess?

We keep the work tidy. We protect what’s around the joints.

Can I do it myself?

You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.

Do you have insurance?

Yes. Full insurance covers our work, and we can confirm the details when we quote.

Will the old sealant be removed?

Do you work for letting agents?

What the job involves on each surface

Bathrooms and en suites

Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out with baths filled first.

Show homes

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

DIY versus a professional finish

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

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.

New homes and floors in Penpont

Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.

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

Why deal with it now?

The builder is usually the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Why book with us

  • Anti-fungal silicone where joints get wet
  • A choice of colours where the product allows
  • We leave the area clean and tidy
  • A sealant colour to suit the surroundings

Signs you need new build mastic in Penpont

New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart and the sealant has to cope with the movement.

Look out for these signs:

  • Sealant that never bonded to the surface
  • Worktop and upstand sealant coming away
  • Untidy sealant flagged on a snagging list
  • Leaking shower tray seals in a new home

Whether the job is in Penpont itself or nearby, the right material for each joint matters as much as a neat finish.

Questions to ask before you book

  • How much experience the applicator has
  • How the surfaces are prepared before sealing
  • The length of the guarantee
  • What happens if the job turns out different

Our hiring checklist

Keeping the joints in good condition

So the new joints stay in good condition:

  • Avoid running a DIY bead over the old one
  • Use the extractor fan every time you shower
  • Keep water off fresh sealant until it has cured
  • Do not wait for the house to settle if water is getting through

Don’t stand on the bath edge or the lip of the tray. Report any movement in a bath or tray.

A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant.

The process

You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes a few hours in a single home in most cases. Outside jobs in Penpont need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.

  1. We start by going through the snagging items or plot schedule with you.
  2. The failed sealant is removed completely, with no layer left behind.
  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

  • Mention any tricky access
  • Let us know if you’ve seen damp or leaks
  • Let us know about earlier repairs to the joints
