When it isn’t the sealant

We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:

  • Damaged sanitaryware that needs replacing
  • Fire risk assessments or certification
  • A broken extractor fan behind the mould problem

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

Commercial sealant in Sunningdale, done properly

Wet areas get anti-fungal sanitary silicone, and kitchens get a food-safe product where it’s needed. We use sealants from Arbo and Everbuild, chosen to suit each joint. We work on student & care accommodation, retail & leisure sites and office washrooms & kitchens, and the jobs we see most are split sealant around staff kitchen worktops and sinks and leaks from showers into rooms or ceilings below.

Community buildings, schools and small businesses around places like Sunningdale have washrooms and kitchens that see a lot of use. Their sealant and fire-rated joints are as important as those in any bigger building.

You get a 12-month guarantee, the same in Sunningdale as everywhere else we work.

Commercial sealant in Sunningdale: 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 Holy Trinity CofE Primary School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours. Letting a property close to Sunningdale station? Then several rental properties can be resealed on one programme.

Keeping the joints in good condition

So the new joints stay in good condition:

  • Include the silicone on your room checklists
  • Log resealing so you know what’s due
  • Pass on the cure time to whoever cleans the rooms
  • Book larger programmes for quieter times of year

Make it easy for staff to flag a failing joint. Catching one split early can save a leak later.

A room that can’t be let or used is lost income. Catching faults early means they can be put right in a short window, before they become leaks that take the room out of use.

How the visit works

All our tools and materials come with us in the van. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours for a single washroom, longer for a whole building. For a job in Sunningdale, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. The first visit is a look round the site to agree the scope.
  2. Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
  3. Each area is protected and stripped of old sealant.
  4. Once dry, every joint is resealed and tooled.
  5. Housekeeping or site staff are told when each area can be used.

Preparing for the visit

  • Mention any leaks or damp you’ve noticed
  • Tell us about access, such as stairs, a lift or high-level joints
  • For business premises, tell us about site rules or sign-in

Advice

What we’re called out for in Sunningdale

A rushed reseal between guests rarely lasts. 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’re asked about most:

  • Joints that need doing before an inspection or audit
  • Washroom sealant that looks dirty however often it’s cleaned
  • Too many rooms to reseal without closing the building
  • Shower leaks reaching the floor below

Community buildings like Holy Trinity Church are part of the picture too: its kitchen and washroom sealant needs looking after like anywhere else.

Sunningdale questions

Is Sunningdale in your area for commercial sealant?

Yes, Sunningdale is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear quote.

Will you come out to Sunningdale?

Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Are you an approved applicator?

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

How soon can a room be used after resealing?

It depends on the product, but around 24 hours is typical. Housekeeping get the cure time for each room.

What sealant do you use?

It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.

Is it OK to seal over old sealant?

No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.

Will there be a smell?

That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.

Will it make a mess?

We keep the work tidy. We protect what’s around the joints, and we clear up when we are done.

DIY versus a professional finish

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

The difference is mostly in the preparation and the 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.

Landlords, agents and businesses in Sunningdale

For anyone letting property in or around Sunningdale, several properties can go on one quote. Just tell us the addresses and what each one needs, and pictures by email help.

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

Leave it or put it right?

Guests and staff judge a building by its bathrooms. Black sealant makes a clean room look dirty, and cleaning rarely puts it right. Replacing it does. Around Sunningdale, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.

The cost reflects the work involved, not guesswork. That’s why we ask about the job first and send you a clear quote before any work starts.

What you get with us
