What affects the cost of commercial sealant

We quote each job individually. This is what makes a difference:

  • The old material and how stubborn it is
  • Any working-time requirements on site
  • Which sealant suits the joint
  • Access and height

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

What we need to know

When you call or email, these details help:

  • A few photos by email, if you can
  • What’s wrong with the joints now
  • If it’s domestic, commercial or a hotel
  • Where the job is, and your postcode

Every job is quoted individually, so the first step is telling us about yours. Just call 0345 464 0079 or send us an email with the details, and photos are welcome.

Commercial sealant in Greenham

With over 20 years in sealant work, we are a fully insured, ARBOMaster approved team. If your site needs RAMS or insurance details, tell us, and we will confirm what we can supply with the quote. We’re often asked to deal with washroom sealant that looks dirty however often it’s cleaned and mouldy bathrooms flagged at a tenancy check, on welfare facilities, rental portfolios and retail & leisure sites.

In a village or hamlet like Greenham, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.

You get a 12-month guarantee, the same in Greenham as everywhere else we work.

Honest limits

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

  • A shower tray, bath or basin that is cracked or broken
  • Extraction that isn’t working, which needs an electrician or ventilation contractor
  • Failed tanking or loose tiles behind the sealant

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

Surfaces we seal

Greenham: your questions answered

Do you work in hotels near Greenham?

Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.

Can you help a landlord with a rental near Newbury Racecourse station?

Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.

Does someone need to be in?

Access is agreed with you when the job is booked. For inside work, that normally means someone being in.

What should I tell you?

Let us know what needs doing and where. We’ll ask anything else we need to know.

Will it make a mess?

No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.

Can you quote for more than one area?

Yes. Several rooms, windows or areas can go on one quote.

Do you work in Greenham?

Yes. We’re based in Crawley and work across South East England, London and Scotland, and that includes Greenham.

Do the sealants smell?

Possibly a little. Any smell clears as the sealant cures.

How the visit works

All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we have agreed what’s being done, we protect the area and start. It normally takes as long as the scope needs, from one welfare room to a full building. Somewhere as small as Greenham, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. The first visit is a look round the site to agree the scope.
  2. Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
  3. Each area is protected and stripped of old sealant.
  4. Once dry, every joint is resealed and tooled.
  5. Housekeeping or site staff are told when each area can be used.

Getting ready for the visit

  • Keep children and pets away from the work area
  • Mention if the joints have been sealed before
  • Try not to wet indoor joints just before the visit

Getting a quote

There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or send us an email.

Related advice

Can I do it myself?

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Leave it or put it right?

Room by room, the work is quick: it takes a few hours for a single washroom, longer for a whole building. After that, each area needs its cure time before use, so the programme is planned around cure times. Older cottages and farmhouses around Greenham can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.

Aftercare tips

After the cure time, these simple habits help:

  • Log resealing so you know what’s due
  • Get split or lifting joints looked at early
  • Plan resealing around quiet periods
  • Ask cleaners to go gently on the silicone

Daily cleaning with harsh chemicals shortens the life of any sealant. Ask cleaners to use mild products and soft cloths on the sealant.

Water from a failed shower seal can travel: through floors, into ceilings and across into corridors. Early resealing keeps it from getting that far.

Commercial sealant in Greenham: local notes

There are hotels and other places to stay in and around Greenham. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

Letting a property close to Newbury Racecourse station? Then we can quote for one property or a whole portfolio of rentals. For site and facilities teams at buildings such as The Willows Primary School, busy washrooms and kitchens can be resealed in phases so they stay open. For buildings such as Church of St Mary, any kitchen and washrooms need the same sealant care as any other building.
