How we handle new build mastic in Great Hallingbury

For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. We work on skirting & floors, plot handovers and show homes, and the jobs we see most are messy sealant that spoils new finishes and cracks appearing as a new home settles.

Work in a small place like Great Hallingbury just needs the journey and access planning, and once on site, the job is the same as anywhere.

The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

How to look after the new joints

Simple care keeps the joints in good condition. We recommend:

  • Wait for the cure time before using a resealed shower
  • Report sealant problems to your builder during the snagging period
  • Open a window or run the fan after bathing
  • Photograph failed sealant before it’s redone

Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.

Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you, so raise it early.

Leave it or put it right?

It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times. Where a wall is exposed, as many are in small places like Great Hallingbury, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

  • Sealant colour chosen to suit
  • Every job guaranteed for a year

DIY sealant or a professional job?

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

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

What happens on the day

A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. Most jobs take a few hours in a single home. Somewhere like Great Hallingbury needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. First we work through your snagging list or plot schedule with you.
  2. We cut out every bit of the failed or messy sealant.
  3. Each joint is cleaned of dust and grit, then primed if required.
  4. A sealant chosen for each area goes in and is tooled smooth.
  5. We check every joint and tell you how long each needs to cure.

How to prepare

  • Where the joints are inside, avoid wetting them before we arrive
  • Move anything stored near the joints
  • Let us know about stairs, lifts or work at height

Advice

When to call us in Great Hallingbury

New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open, and sealant that can’t keep up splits.

The most common problems we see are:

  • Worktop and upstand sealant coming away
  • Cracks appearing as a new home settles
  • Cracked caulk along new skirting
  • Smeared, uneven beads picked up at snagging

For new homes near Bishops Stortford station, it’s worth checking the sealant early, while snags are still fresh.

10 questions to ask before you book

Great Hallingbury questions

Do you work for landlords with property near Bishops Stortford station?

Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.

Will you come out to Great Hallingbury?

Yes, Great Hallingbury is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Can I do it myself?

Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Why does sealant fail so quickly in new builds?

A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.

How do I get a quote for new build mastic in Great Hallingbury?

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. You’ll get a clear quote before work begins.

Will you leave a mess?

Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.

What sealant do you use?

We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.

Do you take out the old sealant first?

Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
