About our floor joint sealing in Temple Fortune

Where skirting is painted, we can use a flexible sealant that takes paint. For bathrooms and kitchens, silicone is generally the better choice because it handles water. We work on concrete floor joints, commercial floors and skirting boards, and common reasons people get in touch are failed joint filler in concrete floors and gaps opening between the floor and skirting.

Across London, commercial floors have movement joints that break down under heavy foot traffic, while new homes need a neat, sound finish around frames, baths and kitchens before handover, in Temple Fortune and beyond.

The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

FAQs for Temple Fortune

Is Temple Fortune in your area for floor joint sealing?

Yes, Temple Fortune is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.

Is parking an issue for floor joint sealing in Temple Fortune?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.

Can I do it myself?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.

Is there a guarantee?

Yes, always. Each job is guaranteed for twelve months.

Can you do several jobs on one visit?

Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

Can you reseal concrete floor joints in an industrial unit?

Yes. We clean out the joints and reseal them with a product suited to the floor. Let us know about the traffic when you ask for a quote.

Why not just use caulk?

Only on dry joints that do not move. Caulk cracks as the floor moves. A flexible sealant is the better choice.

Do you have insurance?

Yes. We are fully insured for every job we do.

What floor joint sealing looks like in Temple Fortune

Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent. Floors around Greater London run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. That is why the skirting and threshold joints need a flexible seal.

For buildings such as Saint Mary and Archangel Michael Church, floor and skirting joints in halls and kitchens wear like any others. Temple Fortune is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

What we’re called out for in Temple Fortune

A new floor or screed shrinks and settles as it dries. Gaps at the edges appear in the first year or so, and rigid fillers crack.

The most common problems we see are:

  • Cracked grout where a tiled floor needs a movement joint
  • Floor edges that trap water and grime
  • Chipped and open joints in warehouse floors
  • Gaps at thresholds between rooms

Schools such as Garden Suburb Infant School are buildings too, and floor and threshold joints in busy corridors wear quickly and are best resealed early.

Questions to ask before you book

  • Who turns up on the day
  • How hidden problems are handled
  • How long to leave it before use
  • Whether they seal over old material or remove it

Our hiring checklist

What affects the quote in Temple Fortune

Every job gets its own quote. This is what makes a difference:

  • The number of rooms or windows
  • The product the joint needs
  • The number and length of the joints
  • Any working-time requirements on site

A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Asking for a quote

What to tell us when you ask for a quote:

  • If it’s domestic, commercial or a hotel
  • Whether it has been sealed before
  • The rough size of the job
  • The address or postcode of the job

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.

Can I do it myself?

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

The process

We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours, depending on the length of joint and we leave things clean and tidy. In a London area like Temple Fortune, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.

  1. We look at the gap and the floor type and agree the right sealant.
  2. We take out any old caulk, sealant or grout along the line.
  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. The joint is tooled to a neat finish and we tell you when it can take feet and a mop.

Before we arrive

  • Keep pets and children clear of the area while we work
  • Let us know about stairs, lifts or work at height
  • Tell us if parking is tricky

Honest limits

Some problems need a builder, plumber or other trade rather than us:

  • Large cracks that need a surveyor
  • Water getting under the tiles from elsewhere
  • A tiled floor that needs relaying

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

What we seal

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

Why deal with it now?

Leaving skirting gaps until the next decorating job lets dirt and draughts in. It’s a quick job to seal them now in most rooms. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.

Doing several joints on one visit usually makes better use of the time than several visits. We will send you a clear quote for the lot.

Why Temple Fortune clients choose us

  • Colour picked to suit the job
  • Full insurance on every job
  • Anti-fungal silicone where joints get wet
  • Old sealant always removed completely

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can be quoted together.
