Commercial sealant in Loudwater

Commercial sealant in Loudwater, done properly

In a hotel, office or washroom, failed sealant is more than an eyesore. It’s a cleaning problem, a leak risk and something guests and staff notice. Our applicators renew sealant across washrooms, welfare areas, kitchens and guest bathrooms. If you’re dealing with washrooms that need sorting before an inspection and washroom sealant that looks dirty however often it’s cleaned, we can help, whatever the surface.

If you have holiday lets, a converted barn used for business or a community building near Loudwater, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

A one-year guarantee comes as standard, so you are not left on your own once the job is done.

Can I do it myself?

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

What we’re called out for in Loudwater

Quick fixes come back quickly. New silicone over old, joints that weren’t dried, or an unsuitable product all lead to the same thing: another reseal before long.

These are the problems we are asked about most:

  • Failed joints in office kitchens and tea points
  • Split sealant where wet room floors meet walls
  • Tired sealant in let properties
  • Large numbers of bathrooms needing the same work

For landlords with property near Rickmansworth station, we can quote for one property or a whole portfolio of rentals.

Commercial sealant in Loudwater: local notes

Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

If you look after a building such as Christ Church Chorleywood CofE School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours. Community buildings like Christ Church are part of the picture too: its kitchen and washroom sealant needs looking after like anywhere else.

FAQs for Loudwater

I let a flat near Rickmansworth station. Can you help?

Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.

Can you do commercial sealant in Loudwater?

Yes. Our work covers London and the South East, and Loudwater is part of that. You can call 0345 464 0079 or email us and let us know what needs doing.

Can I do it myself?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Do you provide RAMS?

Let us know which documents your site needs, such as method statements, risk assessments or insurance details, and we will confirm what we can provide when we quote.

How long do rooms need to be out of use?

Plan for around 24 hours, or the cure time we give for that area. A room-by-room programme keeps only a few rooms out at once.

Is it OK to seal over old sealant?

No, it will not last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.

Do you guarantee commercial jobs?

Yes. We give a 12-month guarantee on every job and are fully insured.

Are you ARBOMaster approved?

Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.

For landlords and businesses

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.

From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.

When it is not the sealant

We’ll always be straight with you, so here’s what new sealant won’t do:

  • Failed tanking or loose tiles behind the sealant
  • Cracked trays or baths rather than failed joints
  • Fire risk assessments or certification

Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly.

What happens on the day

We keep the work tidy and contained to the area we’re working on. The job normally takes a few hours for a single washroom, longer for a whole building. In a small place like Loudwater, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We start with a site walk to agree the rooms and the timing.
  2. Each area is protected and the old sealant cut out completely.
  3. The joints are degreased, treated and left to dry.
  4. Anti-fungal sanitary silicone goes into wet areas, with suitable sealants elsewhere.
  5. Rooms are checked and returned with a cure time so staff know when to use them.

Preparing for the visit

  • Plan for the work area to be out of bounds to pets and children
  • Tell us if parking is tricky
  • Clear the area around the work

What happens if it’s left?

Replacing a whole washroom takes time, money and several trades. When the fittings are sound, renewing the sealant brings it back with far less upheaval. If something else is wrong, we’ll say so. Older cottages and farmhouses around Loudwater can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

There are no prices on our website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or drop us an email and we will talk you through it.
