How we handle commercial sealant in Colchester

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. If you’re dealing with leaking joints in shower rooms and changing areas and shower leaks reaching the floor below, we can put it right.

A place the size of Colchester has offices, shops, hotels and schools, each with its own washrooms, kitchens and fire-rated joints to look after. We cover both day-to-day sealant and fire-rated sealant, installed to the manufacturer’s tested details.

Every job comes with our 12-month guarantee, wherever you are in Essex.

Questions from Colchester

Do you work for hotels and guest houses in Colchester?

Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.

Do you cover Colchester for commercial sealant?

Yes, Colchester is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing.

Is there a guarantee?

Yes. There’s a 12-month guarantee on every job, wherever you are.

How much does commercial sealant cost in Colchester?

Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or email us and let us know what needs doing and where.

Where is Mr Mastic based?

We work from Crawley. We cover Colchester and the rest of Essex.

How long does commercial sealant take?

That depends on the amount of work, but most jobs take anything from a few hours to several days, depending on the number of rooms. We will give you a better idea when we quote.

Will you leave a mess?

No. We work neatly, protect the area around the joints and tidy up afterwards.

When can guests or staff use the shower again?

Generally after around 24 hours. We give a cure time for each area.

DIY versus a professional finish

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, then guaranteed for a year.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Keeping the joints in good condition

Looking after new joints is easy, and it makes a real difference:

  • Check extract fans are actually running
  • Note the date each area was done
  • Give housekeeping the cure time for every room
  • Leave squeegees in busy showers

A squeegee in each shower is a simple help: less water sits on the joints between uses.

Rooms out of use cost a hotel or landlord money. Catching faults early means they can be put right in a short window, before they become leaks that take the room out of use.

Quotes for commercial sealant in Colchester

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

  • The product the joint needs
  • Working hours on commercial sites
  • How much old sealant there is and how hard it is to remove
  • Any mould that needs treating

Doing several joints on one visit is normally more efficient than separate visits. You will get one clear quote for the whole job.

What to tell us for a quote

A few details help us give you an accurate quote. When you get in contact, it helps to mention:

  • Pictures of the joints, sent by email
  • How many joints, rooms or windows are involved
  • Where the property is
  • How we’d reach the joints

Getting a quote is simple: tell us what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand, and we will take it from there.

What the job involves on each surface

Student & care accommodation

In care settings, we agree the order and timings with staff, and staff are told when each bathroom can be used.

Office washrooms & kitchens

Long vanity tops have joints that hold water and grime. It’s cut out, cleaned and resealed in one neat line.

Do you need commercial sealant in Colchester?

Shower trays and baths in busy buildings move more: people of all sizes, daily cleaning and constant loading all work at the joint. A tray that is not fully supported soon tears its seal.

If you can see any of these, it’s time to have the joints looked at:

  • Leaks from showers into rooms or ceilings below
  • Too many rooms to reseal without closing the building
  • Rental bathrooms that need resealing between tenants
  • Leaking joints in shower rooms and changing areas

If you look after a building such as Colchester Sixth Form College, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.

Before you book anyone

  • Who turns up on the day
  • How the joint is cleaned and prepared
  • What product goes in the joint
  • Whether VAT is included

Our hiring checklist

When it is not the sealant

New sealant can’t fix everything, and we’ll tell you before any work starts. It will not solve:

  • Damaged sanitaryware that needs replacing
  • Leaking pipework, valves or wastes (a plumber’s job)
  • Assessing what fire stopping a building needs

If in doubt, call 0345 464 0079 or send us an email and we will say what we think before you book.

What we seal

  • Office washrooms & kitchens
  • Hotel bathrooms
  • Retail & leisure sites
  • Welfare facilities
  • Student & care accommodation
  • Rental portfolios

The process

Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a single washroom, longer for a whole building. In Colchester, we work in everything from flats and family homes to offices and hotels. Whichever it is, tell us how to get in, where to park and where the work is.

  1. We start with a site walk to agree the rooms and the timing.
  2. Every area is sheeted and the old silicone stripped out.
  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

  • Keep pets and children clear of the area while we work
  • Clear the area around the work
  • For business premises, tell us about site rules or sign-in
