How we handle floor joint sealing in South Lambeth

Gaps along the bottom of skirting are common in new and older homes alike. Decorators’ caulk normally cracks where there’s movement, so we use a flexible sealant that moves with the floor. Common call-outs are for failed joint filler in concrete floors and gaps opening between the floor and skirting, across commercial floors, concrete floor joints and wet room & bathroom floors.

Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, and new homes need their plot mastic finished properly before handover.

All our work comes with our one-year guarantee.

DIY versus a professional finish

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

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 fails, we can still redo it.

How the visit works

At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours for most rooms, longer for large commercial floors, depending on how much there is to do. In South Lambeth, 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. Old caulk, grout or sealant is removed from the joint.
  3. We clean and vacuum the joint and fit backing where the depth needs setting.
  4. The sealant goes in, chosen for the floor and coloured to suit it.
  5. The joint is tooled to a neat finish and we tell you when it can take feet and a mop.

How to prepare

  • Tell us about any water getting in
  • Mention any parking rules near the property
  • On commercial sites, let us know about site rules

Floor joint sealing in South Lambeth: 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. 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. The joint at the skirting or threshold has to allow for that.

As a London address, South Lambeth can be tricky for parking: let us know about parking bays, permits or a driveway. For buildings such as St Stephen's Church, floor and skirting joints in halls and kitchens wear like any others. If you let a flat or house near Vauxhall station, gaps at skirtings and thresholds are worth sealing between tenancies.

Landlord and commercial work in South Lambeth

For anyone letting property in or around South Lambeth, jobs at different addresses can be quoted together. Send us the addresses and the work at each, and pictures by email help.

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.

Leave it or put it right?

Open joints along wet floors let water into the subfloor and behind skirting. Sealing them now keeps the problem at the surface. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.

Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

  • Old sealant always removed completely
  • Sealant colour chosen to suit

Your questions about floor joint sealing in South Lambeth

Is parking a problem for a job in South Lambeth?

London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.

Do you work for landlords with property near Vauxhall station?

Yes, we work for landlords and agents. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.

Can you match the sealant colour?

Most of the time, yes. We will explain which colours are available.

Can I do it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Do you come to South Lambeth?

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

Do you seal warehouse floor joints?

Yes, including warehouses, units, shops and offices. We can plan around your opening times with out-of-hours work where needed.

Do you use a paintable sealant?

On joints you want to paint, yes. Silicone does not take paint, so tell us your plans.

How long will you be here?

It depends on the size of the job, but most jobs take a few hours for most rooms, longer for large commercial floors. We will tell you when we quote.

Keeping the joints in good condition

Good habits help new joints last longer. Our tips:

  • Ask before painting over a sealed joint
  • Mark off resealed joints in warehouses
  • Don’t fill floor joints with caulk where they move or get wet
  • Look at floor joints each spring

Lift furniture rather than sliding it over sealed joints. Dragging can tear the bead before it has fully cured.

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.
