Questions from Cothill

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

Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.

Do you cover smaller places like Cothill?

Yes. Cothill is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you seal floor joints in bathrooms and kitchens?

Yes. Wet-area floor joints are sealed with a flexible, water-resistant silicone so water cannot get into the gap.

Do you take out the old sealant first?

Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.

Where do you work from?

Our base is in Crawley, and we cover South East England, London and all of Scotland.

Are you an approved applicator?

Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.

Can you use decorators’ caulk instead?

Not where the floor moves or gets wet. Caulk cracks as the floor moves and the gap reopens. A flexible sealant is the better choice.

Is it OK to seal over old sealant?

No, it will not last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.

Floor joint sealing for homes and businesses in Cothill

Every floor moves a little, so its edges need a joint that can flex. We seal skirting gaps, tiled floor movement joints and concrete floor joints with a sealant suited to the movement and traffic. We work on concrete floor joints, wet room & bathroom floors and commercial floors, and people most often call us about gaps at thresholds between rooms and grout cracking in a straight line across a floor.

Around Cothill, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.

You are covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or email us.

How it works

The work is kept neat and contained to the joints we are treating. The job generally takes a few hours, depending on the length of joint, and we explain the cure time before we leave. In a small place like Cothill, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. First we check the joint and the floor and agree which sealant suits it.
  2. Old caulk, grout or sealant is removed from the joint.
  3. The joint is vacuumed clean, with backing fitted wherever depth matters.
  4. We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
  5. We tool the joint neatly and tell you when it can be walked on and cleaned.

Preparing for the visit

  • Mention any leaks or damp you’ve noticed
  • Tell us about access, such as stairs, a lift or high-level joints
  • Plan for the work area to be out of bounds to pets and children

Advice

What we can’t put right

In fairness, there are a few things sealant won’t fix:

  • Large cracks that need a surveyor
  • Subfloor problems that need a flooring contractor
  • Concrete repairs beyond the joint

Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before booking.

Where we work in Cothill

  • Skirting boards
  • Commercial floors
  • Tiled floors
  • Concrete floor joints
  • Wet room & bathroom floors
  • Thresholds

Looking after it afterwards

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

  • Avoid sloshing water against skirting
  • Keep heavy wheels off new concrete joints until cured
  • Keep dirt out of the joints
  • Ask before painting over a sealed joint

Keep off the joint for the time we give you. Feet are usually fine before mopping or wheeled traffic so we’ll give you each time.

Cracks along tile grout lines come back unless the movement is dealt with. Adding a movement joint early can stop cracks spreading to the tiles.

For landlords and businesses

If you manage several properties in or around Cothill, several properties can go on one quote. Send us the addresses and the work at each, and photos by email help.

Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

Should I try it myself first?

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

When to call us in Cothill

When a tiled floor has no movement joints, the grout takes the strain. Cracks often run straight along a line of joints, showing where a movement joint was needed.

People generally contact us when they notice something like this:

  • Gaps at thresholds between rooms
  • Chipped and open joints in warehouse floors
  • Caulk that has cracked where the floor moves
  • Perimeter joints in tiled floors filled with grout

Rented homes near Radley station change hands often, and a tidy floor and skirting joint helps a rental look ready for the next tenant.

Floor joint sealing in Cothill: local notes

Across Oxfordshire, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. That is why the skirting and threshold joints need a flexible seal.

For site and facilities teams at buildings such as Dry Sandford Primary School, entrance and corridor floor joints take a lot of traffic. Community buildings like Church of St Helen are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.

What happens if it’s left?

Leaving skirting gaps until the next decorating job lets dirt and draughts in. Sealing them now is a short job in most rooms. Where a wall is exposed, as many are in small places like Cothill, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll go through it with you.

What you get with us

  • We leave the area clean and tidy
  • Anti-fungal sanitary silicone in wet areas
