About our floor joint sealing in Sands End

In commercial and industrial units, concrete floor joints take a hammering from wheels and traffic. Each is resealed with a floor-joint product suited to what runs over it. If you’re dealing with gaps between floors and kitchen plinths and dirt and water collecting in open floor joints, we can put it right, whatever the surface.

London homes range from new-build flats to period conversions with new floors laid over old boards. Every joint between floor, skirting and threshold has to cope with some movement.

There’s a 12-month guarantee on every job, large or small.

How it works

We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most rooms, longer for large commercial floors. In Sands End, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.

  1. We start by looking at the floor, the gap and the traffic, then choose the product.
  2. Whatever is in the joint now, whether caulk, grout or sealant, comes out.
  3. The joint is vacuumed clean, with backing fitted wherever depth matters.
  4. A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
  5. We tool the joint neatly and tell you when it can be walked on and cleaned.

Preparing for the visit

  • Let us know about earlier repairs to the joints
  • Keep pets and children clear of the area while we work
  • Try not to wet indoor joints just before the visit

FAQs for Sands End

Can parking be tricky for a visit in Sands End?

Parking in Sands End, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot.

I let a flat near Imperial Wharf station. Can you help?

Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.

How much does floor joint sealing cost in Sands End?

The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.

Do you offer different sealant colours?

Usually, yes. Sealants come in white, clear, grey and other colours for many products, and we will agree it with you first.

Is it OK to seal over old sealant?

No, it won’t last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.

Can you use decorators’ caulk instead?

Because caulk cracks where there’s movement or water. Skirting joints move with the floor, so we use a flexible sealant that stretches.

Will it make a mess?

Not at all. We work neatly, protect the area around the joints and tidy up afterwards.

What information do you need?

Let us know what needs doing and where. If we need more, we’ll ask.

How the job changes by surface

Tiled floors

Perimeter joints in tiled floors should be sealant, not grout. We rake out any grout there and reseal.

Concrete floor joints

We clean concrete joints out thoroughly before sealing, vacuuming them clean. Backing goes in where the depth needs controlling.

Floor joint sealing in Sands End: local notes

Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. Across Greater London, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they don’t all move the same way. The joint at the skirting or threshold has to allow for that.

Sands End is in London, so parking needs planning: let us know about parking bays, permits or a driveway. Community buildings like St Mary's Church are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.

Sands End is about 2 miles south-west of Brompton, in Greater London. Across the SW11 area, we cover floor joint sealing for homes and businesses. Sands End is one of 764 towns and villages in Greater London we cover.

Work in SW11, SW6 and SW10 works the same way as everywhere else we cover.

How we quote for floor joint sealing

Call for a quick quote. The main things that affect it are:

  • Any mould that needs treating
  • The size of the job
  • The product the joint needs
  • How easy the joints are to reach

What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and agree the price before starting.

What to tell us for a quote

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • Where the property is
  • What the problem is, such as mould, gaps, leaks or cracking
  • Photos by email, if that is easy

Work for landlords, hotels and businesses

For anyone letting property in or around Sands End, jobs at different addresses can be quoted together. Send us the addresses and the work at each.

Landlords and letting agents in Sands End can book us as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.

Should I try it myself first?

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.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

What we’re called out for in Sands End

New floors settle once they’re in use. Gaps at the edges appear in the first year or so and anything rigid cracks.

Look out for any of the following:

  • Tiled floors with no room to move
  • Failed joint filler in concrete floors
  • Caulk that has cracked where the floor moves
  • Worn sealant at door thresholds

Managing a site like Falconbrook Primary School? Then entrance and corridor floor joints take a lot of traffic.

How to choose a mastic man

Leave it or put it right?

Dirt builds up in open joints, and they look untidy. Sealed joints are easier to keep clean and finishes the floor. In a flat in Sands End, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
