Trusted floor joint sealing in Peckham

Should I try it myself first?

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

Floor joint sealing in Peckham, done properly

Good floor joints come down to the right product and clean, prepared edges. Old caulk, grout or failed sealant comes out first, then clean, back and seal the joint. We work on tiled floors, commercial floors and thresholds, and people most often call us about perimeter joints in tiled floors filled with grout and cracked caulk along skirting in bathrooms and kitchens.

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.

There’s a 12-month guarantee on every job.

Work for landlords, hotels and businesses

Housing providers, facilities teams and property managers book us too in Peckham and across Greater London. We can quote a run of properties together, and we are fully insured for the work.

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

Leave it or put it right?

Left open, concrete joints break down under traffic. Resealing it early protects the edges before they need a bigger repair. 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 for homes in Peckham.

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.

Why book with us

  • Tidy, careful work
  • Colour picked to suit the job
  • Quality sealants from Arbo and Everbuild
  • White, clear, grey or another colour, product permitting

Surface by surface

Skirting boards

Skirting pulls away from the floor as floors shrink and settle. A flexible sealant closes the gap without cracking painted or coloured to match.

Concrete floor joints

Concrete floors have sawn or formed joints to control cracking. They’re resealed with a product chosen for what runs over them.

What happens on the day

There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours, depending on the length of joint for a typical job. In Peckham, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.

  1. We look at the gap and the floor type and agree the right sealant.
  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.

Before we arrive

  • For indoor joints, keep the area dry beforehand if you can
  • Let us know about earlier repairs to the joints
  • Let us know if you’ve seen damp or leaks

Advice

New homes and floors in Peckham

Across Greater London, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. The joint at the skirting or threshold has to allow for that. Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent.

Letting a property close to Queens Road Peckham station? Then a tidy floor and skirting joint helps a rental look ready for the next tenant. Community buildings like All Saints Church are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.

Looking after it afterwards

Good habits help new joints last longer. Our tips:

  • Ask before painting over a sealed joint
  • Sweep along the edges of the floor
  • Do not slide heavy items over sealed joints
  • Avoid caulk in bathrooms and kitchens

Keep heavy traffic off resealed concrete joints for the cure time we give you. Cone off the area if needed.

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.

What we’re called out for in Peckham

Timber floors and skirting shrink and swell through the year. Heating dries timber and opens gaps along the skirting, then close again in damper months.

Most people get in touch after spotting something like this:

  • Grout cracking in a straight line across a floor
  • Failed seals where bathroom floors meet baths and panels
  • Chipped and open joints in warehouse floors
  • Worn sealant at door thresholds

Peckham is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Before you book anyone

  • How hidden problems are handled
  • Whether all the old sealant comes out first
  • Which colour the sealant will be
  • Whether VAT is included
