Trusted commercial sealant in Colthrop

Do you need commercial sealant in Colthrop?

Staff kitchens and food areas see constant splashing and wiping, and grease and cleaning sprays break down sealant. The worktop and sink edges normally fail first.

The most common problems we see are:

  • Split sealant where wet room floors meet walls
  • Black, stained silicone in guest bathrooms
  • Shower leaks reaching the floor below
  • Failed joints in office kitchens and tea points

If you look after a church, hall or community building such as St Mary's Church, halls and community kitchens see heavy use, and their sealant shows it.

Questions to ask before you book

  • What the quote includes, VAT included or not
  • How the joint is cleaned and prepared
  • How hidden problems are handled
  • Whether they seal over old material or remove it

Choosing a sealant specialist

Commercial sealant in Colthrop, done properly

In a hotel, office or washroom, failed sealant is more than an eyesore. Cleaners struggle with it, water gets through it and people notice it. Our applicators renew sealant across washrooms, welfare areas, kitchens and guest bathrooms. Common call-outs are for large numbers of bathrooms needing the same work and washrooms that need sorting before an inspection, across retail & leisure sites, welfare facilities and office washrooms & kitchens.

Somewhere as small as Colthrop, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

How to look after the new joints

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Give housekeeping the cure time for every room
  • Leave squeegees in busy showers
  • Get split or lifting joints looked at early
  • Keep a record of which rooms were resealed and when

Extract fans need to work. Where a room has no window, the fan is what dries it out, and mould comes back faster without it.

It’s easier to plan a programme than to react to failures. We can fit the work around bookings, shifts and opening hours, instead of rooms closing without warning.

Why deal with it now?

A quick bead over the old sealant might get a room back in use today, but silicone doesn’t bond to silicone, so it lifts. Doing it properly once is less disruptive than doing it badly twice. In a small place like Colthrop, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

What it costs depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before any work starts, so you know where you stand.

Why us?

  • Sealant colour chosen to suit
  • We leave the area clean and tidy
  • An ARBOMaster approved applicator
  • We are fully insured

What affects the cost of commercial sealant

Your quote is based on your job. We look at:

  • The old material and how stubborn it is
  • How easy the joints are to reach
  • When we can work, for business premises
  • The type of sealant required

Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What to tell us for a quote

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • If it’s domestic, commercial or a hotel
  • Photos by email, if that is easy
  • Roughly how big the job is
  • The address or postcode of the job

We don’t publish a price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To arrange one, phone 0345 464 0079 or send us an email.

How the visit works

At the end, we look at the finished work together. The visit itself usually takes a few hours per area, with larger sites planned over several visits, depending on the amount of work. Somewhere like Colthrop needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. We agree a programme with you: which rooms, in what order, at what times.
  2. We go through your site’s paperwork needs, such as RAMS, before work begins.
  3. In each room, the old bead comes out and the joint is cleaned and treated.
  4. We reseal with the right product for each joint.
  5. Each finished area is checked with you and given a cure time.

Before we arrive

  • Tell us about any water getting in
  • Let us know about stairs, lifts or work at height
  • Try not to wet indoor joints just before the visit

How to get a quote

Asking for a quote is easy: let us know the job and the location and its rough size. A few photos by email make the job easier to understand, and we’ll take it from there.

Common questions in Colthrop

I let a flat near Thatcham 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.

Do you cover Colthrop for commercial sealant?

Yes, Colthrop is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear price.

What does commercial sealant cost?

Size, access and the old material all affect the cost. Call for a quick quote.

Do you remove the old sealant?

Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.

Where do you work from?

Our base is in Crawley, and we cover South East England, London and all of Scotland.

When can guests or staff use the shower again?

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, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.

What do you need from me for a quote?

Only a few details: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or email us.

Different surfaces, different methods

Student & care accommodation

Empty rooms between terms or tenancies are easy to reseal, but occupied rooms can be planned in as well.

Rental portfolios

A sound seal protects the property as well as its appearance, especially where you rarely see the bathroom yourself.
