Common problems we fix in Waterhall

Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak.

Look out for these signs:

  • Gaps opening as the house dries out and settles
  • Plot mastic for developers ahead of handover
  • Untidy sealant flagged on a snagging list
  • Skirting joints opening in the first winter

If you’ve bought a new home near Preston Park station, the sealant around baths, showers and frames is worth checking in the first year or two.

How to choose a mastic man

What new build mastic looks like in Waterhall

Waterhall is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

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

Yes, Waterhall is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.

Will you come out to Waterhall?

Yes, Waterhall is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Do you work for developers?

Yes. Plot mastic and second-fix sealing for developers is part of our work. Send the schedule and any specification and we’ll give you a quote.

Why does sealant fail so quickly in new builds?

New homes dry out and move in their first couple of years, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.

Can landlords and businesses book you?

Yes. We work for homeowners, landlords, letting agents, businesses and hotels across Brighton and Hove.

How long does the job take?

As a guide, most jobs take a few hours in a single home. Larger jobs naturally take longer, and we will tell you how long to expect.

Is there a guarantee?

Yes. There’s a 12-month guarantee on every job, wherever you are.

Are you an approved applicator?

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

How to look after the new joints

After the cure time, these simple habits help:

  • Watch for new gaps as the house dries out
  • Wipe joints with warm soapy water
  • Avoid running a DIY bead over the old one
  • Ventilate bathrooms well, especially in the first year

Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents as they wear the bead.

Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in saves a harder job later.

What we do, step by step

Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself generally takes anything from a few hours to several days, depending on the number of plots, depending on the size of the job. For a village or hamlet like Waterhall, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
  2. We cut out every bit of the failed or messy sealant.
  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. Each area is checked and left with its cure time.

Getting ready for the visit

  • Let us know if you’ve seen damp or leaks
  • Clear the area around the work
  • Keep children and pets away from the work area

Advice

Can I do it myself?

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

How we quote for new build mastic

Call for a quick quote. The main things that affect it are:

  • The old material and how stubborn it is
  • The type of sealant required

What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts.

What we need to know

When you call or email, these details help:

  • Pictures of the joints, sent by email
  • Any previous sealing or DIY work
  • Whether it’s a home or a business
  • What’s wrong with the joints now

We do not publish a price list, because every job is different. Instead, your job gets its own clear quote. To get started, ring 0345 464 0079 or email us.

Landlord and commercial work in Waterhall

We work for letting agents and landlords as well as householders. Sealant work between tenants is a simple way to keep a property in good order.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

Why act early in Waterhall

A quick bead over the top of the old sealant can look fine at first, but it can’t bond to what’s underneath. A lasting seal starts with removing the old one completely. Older cottages and farmhouses around Waterhall can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
