For landlords and businesses

Housing providers, facilities teams and property managers book us too in Mongewell and across Oxfordshire. Several sites can be quoted together, and we’re fully insured.

Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.

How we handle commercial sealant in Mongewell

In student and care accommodation, there are often many near-identical bathrooms. We agree a programme and work through them in order, fitting around residents and staff. We work on hotel bathrooms, rental portfolios and student & care accommodation, and common reasons people get in touch are failed floor-level joints in accessible wet rooms and too many rooms to reseal without closing the building.

Work in a small place like Mongewell is planned ahead, journey included, so it can be fitted around guests, customers or events where possible.

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

Do you need commercial sealant in Mongewell?

In an accessible wet room, water spreads across the floor every use, so the joints at floor level are under water often. A failed joint there can soon let water into the floor or walls.

Common reasons people contact us include:

  • Tired sealant in let properties
  • Whole floors of tired en suites
  • Mouldy washroom sealant that staff and guests notice
  • Worktop sealant that has shrunk and stained

Community buildings like St Mary's Church are part of the picture too: its kitchen and washroom sealant needs looking after like anywhere else.

What your quote should include

  • Which sealant they’ll use, and why
  • What the cure time is
  • Is VAT in the price?
  • What guarantee comes with the work

10 questions to ask before you book

What happens if it’s left?

Patching the worst rooms as complaints come in is hard to manage. A planned programme deals with every room in order, with less disruption and one clear quote. Older cottages and farmhouses around Mongewell can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.

Why book with us

  • We never seal over old sealant
  • Over 20 years’ experience
  • Experience in homes, commercial sites and hotels
  • White, clear, grey or another colour, product permitting

Common questions in Mongewell

Do you work for landlords with property near Cholsey station?

Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.

Is Mongewell within the area you cover?

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

What does commercial sealant cost?

It depends on the job, so we quote each one individually. For a quick quote, phone 0345 464 0079 or drop us an email and tell us what needs doing and where.

Can you supply method statements and risk assessments?

We are fully insured, and we will go through your site’s requirements with you. Send over your requirements and we will confirm what we can provide.

Is it worth trying it myself?

Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.

Is there any odour?

Possibly a little. It fades as the sealant cures, and ventilation helps.

What information do you need?

The location, the problem and the rough size of the job. Photos by email help too.

Will you leave a mess?

Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.

What affects the cost of commercial sealant

You will get a clear quote before any work starts. It’s based on:

The process

Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours per room, so whole buildings are phased, depending on how much there is to do. In a small place like Mongewell, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Tell us the rooms, hours and site rules, and we will plan the programme.
  2. We go through your site’s paperwork needs, such as RAMS, before work begins.
  3. Old sealant is cut out room by room and joints cleaned and treated.
  4. Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
  5. Rooms are handed back in order, each with its cure time.

Before we arrive

  • Mention any parking rules near the property
  • For indoor joints, keep the area dry beforehand if you can
  • Mention if the joints have been sealed before

Advice

When it isn’t the sealant

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

  • Cracked trays or baths rather than failed joints
  • Leaking pipework, valves or wastes (a plumber’s job)
  • Assessing what fire stopping a building needs

If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.

Where we work in Mongewell

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

DIY versus a professional finish

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
