About our floor joint sealing in Charlton

The gap under a skirting board often opens as floors and walls move with the seasons. Caulk tends to crack there, so we close it with a flexible sealant instead. We’re often asked to deal with cracked grout where a tiled floor needs a movement joint and worn sealant at door thresholds, on skirting boards, tiled floors and wet room & bathroom floors.

In smaller places like Charlton, new homes tend to come as small developments or single plots. Each still needs its sealant and floor joints finished properly from day one.

Every job is covered by a one-year guarantee.

What affects the quote in Charlton

Jobs vary more than people expect. The main factors:

  • The type of sealant required
  • Whether there’s mould to deal with
  • Whether old sealant or filler has to be cut out
  • The amount of work

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or email us and we’ll give you an honest view and a quote.

What we need to know

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

  • Any access issues, like height or stairs
  • The problem you’ve noticed
  • The address or postcode of the job
  • How many joints, rooms or windows are involved

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that is easy.

The process

You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours, depending on the length of joint in most cases. For a job in Charlton, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. We clear the edges of the floor so the joints are easy to reach.
  2. Old material is removed from the joint.
  3. We clean and dry the edges of the joint.
  4. We apply a flexible sealant suited to the floor and smooth it.
  5. We check the joints and explain the aftercare.

Before we arrive

  • Clear items away from the joints we are working on
  • Keep pets and children clear of the area while we work
  • Mention any tricky access

Your questions about floor joint sealing in Charlton

What guarantee comes with floor joint sealing in Charlton?

Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.

Do you cover Charlton for floor joint sealing?

Yes. Our work covers London and the South East, and Charlton is part of that. Just ring 0345 464 0079 or email us with a few details of the job.

Do you hold any approvals?

Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.

Do you work on commercial floors?

In most cases you can choose. We’ll explain which colours are available and agree one before work begins.

How long does the job take?

As a guide, most jobs take a morning or an afternoon for most homes. Bigger jobs take longer, and we will say how long yours will take.

Which products do you use?

We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.

Where are you based?

Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.

How the job changes by surface

Tiled floors

When grout cracks along a straight line, the floor is telling you it needs to move. We rake out that line and seal it if it’s in the right place.

Skirting boards

Skirting-to-floor joints are a regular job for us. The old caulk is removed first so the bead sits on a clean surface.

Looking after it afterwards

Looking after new joints is easy:

  • Check skirting joints after the heating season
  • Cone off fresh joints until they’re ready
  • Do not slide heavy items over sealed joints
  • Avoid sloshing water against skirting

Avoid flooding the floor when you clean. Keeping the edges drier helps the sealant last longer.

Open skirting gaps let in draughts, dust and sometimes insects. Sealing it keeps the room tidier and stops it getting worse.

New homes and floors in Charlton

Across Oxfordshire, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they do not all move the same way. The joint at the skirting or threshold has to allow for that.

If you look after a building such as Charlton Primary School, floor and threshold joints in busy corridors wear quickly and are best resealed early. Community buildings like Holy Trinity Church are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.

Why act early in Charlton

Putting new grout into a crack that keeps reappearing doesn’t last. If the floor needs to move there, the grout will crack again. A flexible movement joint is the fix. Homes in smaller places like Charlton can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.

Doing several joints on one visit normally makes better use of the time than several visits. We’ll give you a clear quote for the lot.
