Work for landlords, hotels and businesses

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

Surface by surface

Windows & doors

A frame that keeps leaking may not be the mastic. If the frame joint isn’t the cause, we’ll say so.

Over-sealed & botched joints

Every layer has to come out, including the smears and film on surrounding tiles. Only a clean joint will take a new bead.

What remedial sealant looks like in Harpsden

There are hotels and other places to stay in and around Harpsden. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room. Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.

For landlords with property near Henley-On-Thames station, a joint that keeps failing is best fixed properly while the property is empty. For site and facilities teams at buildings such as Trinity Church of England Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes.

How to look after the new joints

No joint lasts for ever, but care makes a real difference. A few tips:

  • Do not wait for a small gap to become a leak
  • Keep the room well ventilated
  • Clean sealant with mild products only
  • Find out why the sealant failed first

Don’t let anyone seal over it later. New silicone does not bond to old.

A split movement joint lets rain into walls and floors, and the longer it’s left, the more the joint edges break down. A joint with sound edges is far easier to reseal.

Signs you need remedial sealant in Harpsden

Even good sealant ages. Mould grows into the silicone, the surface hardens and the bead shrinks, especially in damp, poorly aired rooms. Then the only fix is removal and a new bead.

Most people get in touch after spotting one of these:

  • Sealant that came away because the surface wasn’t prepared
  • Smears and lumps from a botched reseal
  • Repeat leaks from the same joint
  • Kitchen joints letting water behind the worktop

If you live in an older home near Church of St Margaret, walls and floors in older homes can move, and sealant and grout show it first.

Questions from Harpsden

Do you work in hotels near Harpsden?

Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.

I let a flat near Henley-On-Thames station. Can you help?

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

Is it worth trying it myself?

That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.

Someone resealed my shower and it’s leaking again. Can you help?

Yes. There’s usually a reason: sealant over sealant, movement or another leak, and we deal with the cause first.

How do I get a quote for remedial sealant in Harpsden?

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.

Do you cover Harpsden?

Yes. From our base in Crawley, we cover South East England, London and all of Scotland.

What should I tell you?

Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or send us an email.

What if resealing won’t fix my leak?

In that case, we tell you what we’ve found. A plumber or fitter may be needed before any new sealant goes on.

How we quote for remedial sealant

Jobs vary more than people expect. What affects the quote:

  • Working hours on commercial sites
  • Mould in or behind the old joints
  • How many areas need sealing
  • How much old sealant there is and how hard it is to remove

What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.

Asking for a quote

When you contact us, these details help:

  • Pictures of the joints, sent by email
  • Whether it has been sealed before
  • Where the job is, and your postcode
  • The problem you’ve noticed

Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved before giving you a price.

Why deal with it now?

DIY removal often leaves scratches and a film of residue, and the residue left behind stops the next bead bonding. Careful stripping is where most of our time goes. Older cottages and farmhouses around Harpsden can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or drop us an email and we will talk you through it.

How it works

A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. Somewhere as small as Harpsden, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First we work out whether the problem is the sealant, movement or a leak.
  2. Old beads and residue are removed down to clean surfaces.
  3. We treat any mould and dry the joint thoroughly.
  4. We reseal with a product suited to the joint, backed where needed.
  5. The joint is tooled and you are told about anything else we found.

Preparing for the visit

  • Let us know about stairs, lifts or work at height
  • Keep children and pets away from the work area
  • Try not to wet indoor joints just before the visit
