Commercial sealant near Canterbury

What we do, step by step

Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours per room, so whole buildings are phased. Where a business in Canterbury needs to stay open, out-of-hours working can be arranged, and homes are booked within our usual hours, Monday to Saturday.

  1. First we visit and agree the scope, the sequence and the working hours.
  2. Each area is protected and the old sealant cut out completely.
  3. The joints are degreased, treated and left to dry.
  4. We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
  5. We check every room and give its cure time for housekeeping.

How to prepare

  • Clear the area around the work
  • Let us know about stairs, lifts or work at height
  • Tell us about any previous sealing or DIY attempts

Commercial sealant for homes and businesses in Canterbury

For a rental portfolio, resealing between tenants keeps bathrooms and kitchens presentable. Several addresses can be quoted together. If you’re dealing with whole floors of tired en suites and joints that need doing before an inspection or audit, we can help, on student & care accommodation, retail & leisure sites and welfare facilities alike.

Landlords with flats and shared houses in Canterbury often need both kinds of work: resealing bathrooms and kitchens, and fire-rated sealant where pipes pass through walls. We can quote for a single property or a whole portfolio.

Whatever the size of the job, you get the same 12-month guarantee.

When it isn’t the sealant

Before you book, it’s worth knowing the limits:

  • Extraction that is not working, which needs an electrician or ventilation contractor
  • Certifying fire stopping or building compliance
  • Failed tanking or loose tiles behind the sealant

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

Common questions in Canterbury

Can you help a landlord with a rental near Canterbury East station?

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear quote.

Is Canterbury in your area for commercial sealant?

Yes, Canterbury is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.

How long do rooms need to be out of use?

Most areas can be used after around 24 hours. Each room is handed back with the cure time for the product used.

What should I tell you?

The location, the problem and the rough size of the job. If you can, email a few pictures.

Will there be a smell?

There can be a smell while the sealant cures, but it fades. Opening a window helps.

Where do you work from?

We’re a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.

Can you reseal hotel rooms while we stay open?

Yes. We agree the room order and times with your managers, and each room is handed back with a cure time.

Does commercial work come with a guarantee?

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

How the job changes by surface

Welfare facilities

Shower rooms in welfare blocks get heavy use and need sound joints. We reseal with anti-fungal sanitary silicone, accessible showers included.

Student & care accommodation

Halls and care homes often have many near-identical bathrooms. A room-by-room programme keeps the job efficient.

DIY versus a professional finish

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.

What affects the cost of commercial sealant

Call for a quick quote. What matters most is:

  • Access and height
  • Whether there’s mould to deal with
  • The product the joint needs
  • How much there is to do

No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.

Helping us quote

What to tell us when you ask for a quote:

  • Where the property is
  • The rough size of the job
  • If it’s domestic, commercial or a hotel
  • The problem you’ve noticed

For a quote, phone 0345 464 0079 or email us with the location and a short description of the problem. You will have a clear quote before any work starts.

Landlord and commercial work in Canterbury

Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.

We work for landlords and letting agents as well as householders. Sealant work between tenants keeps a property looking cared for.

Leave it or put it right?

Sealant is easy to forget until an audit or inspection is due. Booking it in good time leaves room for the cure time before the visit, without a last-minute rush. In flats, shops and offices in Canterbury, a failed joint can let water into the unit below or behind a wall, where it’s often found late and is bigger to put right.

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, so you know where you stand.
