Waltham Chase: questions and answers

Do you take on work at healthcare sites like Knowle Hospital?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is Waltham Chase off your patch?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Will you come and look before quoting?

That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.

How do I request a quote?

You can use the quote form on this site; alternatively, call the office on 01277 525 020 or email the details over. Photos, drawings or a joint schedule help us quote quickly.

Are you insured?

Yes. We’re fully insured, and the certificate can go with your quote.

How much does the work cost?

It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.

Is old silicone taken out first?

The failed bead is always removed. Fresh silicone can’t key to an old bead, so sealing over it soon peels.

About our washroom sealing in Waltham Chase

You can’t shut every toilet in an office, school or hotel at once. Work is phased by room or by section, so staff, guests or pupils always have somewhere to go. Give us your site hours and access windows and the phasing is planned around them. If you’re dealing with failed sealant in a tea point or staff kitchen and mould spotting along silicone joints, we can put it right. For commercial sealant work in Waltham Chase, you deal with one contact from quote to sign-off, whether it’s one building or several.

In and around smaller places like Waltham Chase, washroom work is often in halls, pubs, primary schools, care homes and holiday accommodation. Sealant that has gone black with mould normally can’t be cleaned, so it is cut out and replaced.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Maintenance after handover

Regular inspection catches problems early. Specifically:

  • Respect the cure time before reopening each room
  • Clean sealant with gentle products and a soft cloth
  • Keep extract fans working and vents clear
  • Share your site rules when you send details

Squeegeeing showers and trays after heavy use helps. Standing water on a joint all day shortens its life.

Inspectors look at whether kitchen surfaces can be kept clean. Failed sealant around sinks and worktops is easy to put right in good time.

Surface by surface

Basins and vanity tops

Stone and some composite tops need a neutral-cure sealant and we choose a neutral-cure grade for them.

Changing rooms and gyms

Changing rooms can be phased so one stays open. Phasing follows your site hours and access windows.

Our process

At the end of each section, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. For a building around Waltham Chase, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. First, the phasing is agreed so facilities stay open.
  2. Anything behind the joints that needs another trade is flagged.
  3. Old sealant is stripped and the faces prepared.
  4. We reseal with the grade suited to each area.
  5. We confirm reopening times for each washroom.

What we need from you

  • Send your site hours and access windows
  • Agree which areas must stay open
  • Let us know about inductions and permits

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.

Related advice

Why deal with it now?

A failed joint behind a basin or along a shower tray lets water run where it shouldn’t. In a commercial building that can mean damaged boards, stained ceilings on the floor below and odours which costs more to fix than a reseal. Around Waltham Chase, it’s better to renew all the failing joints at once. Send photos of each area and we’ll quote for the lot.

What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.

What you get with us

  • Fixed quotes based on photographs, drawings or a visit
  • Workmanship guaranteed for 12 months
  • RAL and finish matching where the product range allows
  • Over 20 years of commercial sealing

When to bring in a specialist

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

What we’re called out for in Waltham Chase

Sometimes the sealant fails because something behind it is moving or wet: a loose panel, a leaking waste or water coming through the wall. We check for that first and say if it needs a plumber or another trade.

Typical triggers for a call:

  • Complaints from staff, guests or users about tired washrooms
  • Panel joints letting water behind
  • Resealing that didn’t last because the old bead stayed
  • Sealant lifting along a tray edge

En suites at hotels like Meon Valley Hotel, 0.9 miles south of Waltham Chase, are cleaned daily, which wears silicone over time.

What your quote should include

  • What level of public liability insurance do they hold?
  • Is the sealant right for the movement and the substrate?
  • Will CSCS-carded applicators be on site?
  • Whether old or failed sealant will be cut out, not overlaid
