Commercial sealant for homes and businesses in Fareham

Staff facilities can’t be out of action for long. We can plan the work for early mornings or out of hours to keep disruption down. You’re told when each area can be used again. If you have mouldy washroom sealant that staff and guests notice and failed floor-level joints in accessible wet rooms, we can put it right, whatever the surface.

For anyone managing a school, care home, pub or office in Fareham, the sealant in its washrooms and kitchens, and the fire-rated joints around its pipework, all need looking after. Work can be planned around opening hours where needed.

Our work is backed for twelve months.

Honest limits

A few problems are outside what sealant work can do:

  • Leaking pipework, valves or wastes (a plumber’s job)
  • Assessing what fire stopping a building needs
  • Tiles coming off the wall

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

Joints and surfaces we work on

  • Student & care accommodation
  • Welfare facilities

  • Rental portfolios
  • Retail & leisure sites

Should I try it myself first?

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.

If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

What happens on the day

Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a morning for a small washroom, and a planned programme for bigger sites. In Fareham, parking is rarely complicated, though it helps to know about driveways or restrictions, and let us know if the work is upstairs, in a flat or up high outside.

  1. We walk the site with you and agree the rooms, the order and the hours.
  2. Each area is protected and the old sealant cut out completely.
  3. Joints are cleaned, treated for mould and dried.
  4. We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
  5. Each room is checked and handed back with its cure time.

Preparing for the visit

  • Mention any sign-in or site rules at work premises
  • Tell us about access, such as stairs, a lift or high-level joints
  • Let us know about parking restrictions

How we quote for commercial sealant

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • Whether old sealant or filler has to be cut out
  • Access and height
  • The number and length of the joints
  • Which sealant suits the joint

A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

What we need to know

There’s no need for technical detail. It helps if you can tell us:

  • Roughly how big the job is
  • Any access issues, like height or stairs
  • What the problem is, such as mould, gaps, leaks or cracking
  • Photos by email, if that is easy

For a quote, call 0345 464 0079 or drop us an email with the location and a short description of the problem. You’ll have a clear quote before we start.

What commercial sealant looks like in Fareham

If you run a hotel, guest house or holiday let in a coastal place like Fareham, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

For landlords with property near Fareham station, we can quote for one property or a whole portfolio of rentals. For buildings such as St John The Evangelist, any kitchen and washrooms need the same sealant care as any other building.

What we are called out for in Fareham

A rushed reseal between guests rarely lasts. Sealing over old silicone, sealing wet joints or using the wrong product means the joint fails again soon.

Any of these means the joints need attention:

  • Split sealant around staff kitchen worktops and sinks
  • Tired sealant in let properties
  • Mouldy washroom sealant that staff and guests notice
  • Split sealant where wet room floors meet walls

For site and facilities teams at buildings such as St Jude's Catholic Primary School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.

What your quote should include

  • Which sealant they’ll use, and why
  • What guarantee comes with the work
  • How long to leave it before use
  • Which colour the sealant will be

10 questions to ask before booking

Surface by surface

Hotel bathrooms

In a hotel, every bathroom is used and cleaned daily, so joints are finished smooth and sealed with anti-fungal sanitary silicone.

Rental portfolios

Between tenancies is a good time to reseal, so the next tenant moves in to clean, sound joints.

Landlords, agents and businesses in Fareham

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

Common questions in Fareham

Is there a guarantee on commercial sealant in Fareham?

Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.

Can you help a landlord with a rental near Fareham station?

Yes. We work for landlords and agents as well as householders. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.

Where are you based?

Mr Mastic is based in Crawley. Our applicators cover Fareham.

Do you hold any approvals?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.

Do I need to be at home?

If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.

Will there be a smell?

That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.

Is it worth trying it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Do you remove the old sealant?

Yes. We cut out all the old sealant and clean the joint before applying anything new.
