How we handle floor joint sealing in The Burroughs

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 are often asked to deal with open joints around bathroom floor edges and gaps at thresholds between rooms, across commercial floors, concrete floor joints and skirting boards.

Across London, commercial floors have movement joints that break down under heavy foot traffic, and new homes need their plot mastic finished properly before handover.

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

What affects the cost of floor joint sealing

We don’t publish a price list, because jobs vary so much. The quote depends on:

  • Working hours on commercial sites
  • How easy the joints are to reach
  • The number and length of the joints
  • Mould in or behind the old joints

No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

What to tell us for a quote

You do not need to know the technical terms. Just tell us:

  • What the problem is, such as mould, gaps, leaks or cracking
  • Any access issues, like height or stairs
  • Pictures of the joints, sent by email
  • Any previous sealing or DIY work

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.

What happens on the day

On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before we start. The work generally takes a few hours for most rooms, longer for large commercial floors. In a London area like The Burroughs, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.

  1. The room is cleared along the joints so we can reach them.
  2. Old material is removed from the joint.
  3. Edges are cleaned and dried.
  4. A flexible sealant suited to the floor is applied and smooth it.
  5. We check the joints and explain the aftercare.

Preparing for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Mention if the joints have been sealed before
  • Mention any leaks or damp you’ve noticed

Getting a quote

Every job is quoted individually, so start by telling us what you need. Just call 0345 464 0079 or email us with the details, and photos are welcome.

Should I try it myself first?

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

What sealant work can’t fix

Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:

  • A tiled floor that needs relaying
  • Concrete repairs beyond the joint
  • Leaks from a failed tanking system

If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.

Where we work in The Burroughs

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

Floor joint sealing in The Burroughs: local notes

Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent. Across Greater London, 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. That’s why the skirting and threshold joints need a flexible seal.

For site and facilities teams at buildings such as St Joseph's Catholic Primary School, floor and threshold joints in busy corridors wear quickly and are best resealed early. Rented homes near Hendon station change hands often, and gaps at skirtings and thresholds are worth sealing between tenancies.

The Burroughs is about 2 miles south-east of Burnt Oak, in Greater London. Jobs in The Burroughs get the same care as everywhere else we work: old sealant removed completely, careful preparation and a one-year guarantee. The Burroughs is one of 764 places in Greater London we cover. There’s also a page for London, about 8 miles away.

Landlords, agents and businesses in The Burroughs

In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.

The Burroughs: your questions answered

Is The Burroughs in your area for floor joint sealing?

Yes, The Burroughs is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.

Can parking be tricky for a visit in The Burroughs?

Parking in The Burroughs, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.

Can you do several jobs on one visit?

Yes, and it often makes sense. Doing several areas at once is usually more efficient.

Will there be a smell?

Some sealants have a smell while they cure. Ventilation helps.

When can I walk on the floor?

We give you a cure time for each joint. Light use comes first, cleaning and heavy traffic later in most cases.

What does floor joint sealing cost?

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.

Should I try DIY first?

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 hold any approvals?

Yes. Mr Mastic is an ARBOMaster approved applicator.

Do you need floor joint sealing in The Burroughs?

A floor laid tight to the walls has no room to move. It pushes against the walls and skirting as it expands and joints fail.

These are the problems we are asked about most:

  • Threshold joints that have opened or worn
  • Open joints that fill with dirt
  • Grout used at the floor edge instead of sealant
  • Open gaps along the bottom of skirting boards

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

Before you book anyone

  • Who does the work, and how experienced they are
  • When the joint can take water or movement
  • Whether they seal over old material or remove it
  • The length of the guarantee

How to choose a mastic man

Surface by surface

Skirting boards

Gaps between skirting and floor open as timber and floors move. We seal them with a flexible sealant rather than caulk painted or coloured to match.

Thresholds

Thresholds between rooms meet two floors and often a door frame. We seal them with a flexible sealant that suits both sides.
