About our new build mastic in Monkton

A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. We work on windows & doors, plot handovers and skirting & floors, and people most often call us about plot mastic for developers ahead of handover and sealant applied over dusty or wet surfaces.

Around Monkton, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.

Whatever the size of the job, you get the same one-year guarantee.

What affects the cost of new build mastic

Jobs vary more than people expect. The main factors:

  • How easy the joints are to reach
  • The old material and how stubborn it is
  • Mould in or behind the old joints
  • Working hours on commercial sites

Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

Asking for a quote

The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

  • Pictures of the joints, sent by email
  • Where the property is
  • Whether it’s a home or a business
  • Whether it has been sealed before

How the job changes by 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 and baths are filled before sealing.

Kitchens

As a new house dries, worktops and walls shift a little, which opens gaps along the back. A fresh flexible bead closes them.

Keeping the joints in good condition

Once the sealant has cured, a few habits help it last:

  • Open a window or run the fan after bathing
  • Resist patching a failed seal with a tube from the DIY shop
  • Report sealant problems to your builder during the snagging period
  • Wait for the cure time before using a resealed shower

Don’t stand on the bath edge or the lip of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.

Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you, so raise it early.

What we can’t put right

Some problems need a builder, plumber or other trade rather than us:

  • Baths and trays that move too much for sealant to cope with
  • Broken tiles or a split tray
  • Leaks from pipes, valves or wastes, which need a plumber

Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.

What we seal

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

How much does new build mastic cost in Monkton?

There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.

Do I have to be there?

For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.

Can you quote for more than one area?

Yes. Tell us about everything you’d like done.

Do you guarantee your work?

Do you take on second-fix sealing for builders?

Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. Good preparation keeps snagging to a minimum.

My new home is still under warranty. Should I contact you?

While the snagging or warranty period runs, the builder should be your first contact. If it is not sorted, or keeps failing, get in touch with us.

Do you need new build mastic in Monkton?

On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.

If you can see any of these, it’s time to have the joints looked at:

  • Cracked sealant around new window and door frames
  • Untidy sealant flagged on a snagging list
  • Gaps behind new kitchen upstands
  • Joints pulling apart as timber shrinks

Around Monkton, as everywhere, new build mastic is only as good as the preparation behind it.

What your quote should include

  • Whether all the old sealant comes out first
  • Which colour the sealant will be
  • What preparation is included
  • Are they insured?

How to choose a mastic man

How the visit works

Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on the number of plots. In a small place like Monkton, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We look at why each joint failed, including any movement.
  2. Old sealant is cut out and the joints cleaned.
  3. We make sure the joints are dry and prime them if needed.
  4. Baths are filled with water, then the new sealant is applied.
  5. The finished joints are checked and the cure times given.

Getting ready for the visit

  • Mention if the joints have been sealed before
  • Let us know if you’ve seen damp or leaks
  • Clear items away from the joints we are working on

Advice

Why deal with it now?

A tube of sealant from the DIY shop will not fix the cause: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Around Monkton, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
