About our new build mastic in Spring Park

Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. Common call-outs are for skirting joints opening in the first winter and worktop and upstand sealant coming away, on skirting & floors, kitchens and plot handovers.

Much of London’s new housing is flats in larger developments. Snagging there often goes through the developer or managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Do you need new build mastic in Spring Park?

Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints aren’t always given time to dry before the sealant goes on.

It’s worth asking for a quote if you see:

  • Sealant work across a run of new homes
  • Cracks appearing as a new home settles
  • Sealant applied over dusty or wet surfaces
  • Messy sealant that spoils new finishes

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

What to look for in a quote

  • When the joint can take water or movement
  • How hidden problems are handled
  • How the colour is chosen
  • Whether VAT is included

What we can’t put right

New sealant can’t fix everything, and we will tell you before work begins. It will not solve:

  • Disputes or warranty claims with your builder
  • Baths and trays that move too much for sealant to cope with
  • Cracked trays, tiles or worktops

If you’re not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer.

What we seal

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

Aftercare tips

After the cure time, these simple habits help:

  • Don’t seal over failed sealant yourself
  • Use the extractor fan every time you shower
  • Check bath and shower seals every few months as the house settles
  • Avoid scourers and strong chemicals on sealant

Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.

If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.

Quotes for new build mastic in Spring Park

Call for a quick quote. What matters most is:

  • The size of the job
  • How much old sealant there is and how hard it is to remove
  • Mould in or behind the old joints
  • Which sealant suits the joint

Every job is a little different, 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.

Helping us quote

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

  • Where the property is
  • Photos by email, if that is easy
  • Roughly how big the job is
  • If someone has resealed it before

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.

The process

When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. For a job in Spring Park, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.

  1. We go through the snagging list or plot schedule and agree the joints to do.
  2. The old bead comes out in full, with no layer left behind.
  3. We clean off dust from the build and prime the surfaces where the product needs it.
  4. New sealant suited to each joint is applied and tooled neatly.
  5. We check every joint and tell you how long each needs to cure.

Before we arrive

  • Let us know if you’ve seen damp or leaks
  • Move anything stored near the joints
  • Let us know about parking restrictions

Spring Park: your questions answered

Do you cover Spring Park for new build mastic?

Yes, Spring Park is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we will send you a clear quote.

Can parking be tricky for a visit in Spring Park?

London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.

Where are you based?

We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.

Do you work for landlords and businesses?

Yes, we do. We work in homes, commercial premises and hotels.

How long does new build mastic take?

As a guide, most jobs take anything from a few hours to several days, depending on the number of plots. Larger jobs naturally take longer.

Which products 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’ll explain our choice.

Can new sealant go on top of the old bead?

No. We always remove the existing bead, the joint cleaned and primed where needed, and a new bead applied.

Are you ARBOMaster approved?

Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.

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 for the lot. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Spring Park, the repair is bigger than a sealant job.

What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.
