About our floor joint sealing in Gilbert Street

Large tiled floors, and those over underfloor heating, often need movement joints. We can turn a line of grout into a movement joint by replacing it with flexible sealant in a matching colour. If you’re dealing with rigid edge joints in tiled floors and concrete floor joints that have broken down, we can help, whatever the surface.

Older homes in small places like Gilbert Street often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.

We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Leave it or put it right?

Not every floor joint takes the same sealant: flexible sealant for skirting and tiles, silicone in wet areas, and floor-joint products for concrete. Using the wrong one is why many floor joints fail. Older cottages and farmhouses around Gilbert Street can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Surface by surface

Concrete floor joints

Hard wheels break down the edges of open joints. Sealing them supports the edges and keeps dirt out.

Tiled floors

Large or heated tiled floors need room to move. Where needed, a line of grout is replaced with flexible sealant coloured to suit.

FAQs for Gilbert Street

Is Gilbert Street in your area for floor joint sealing?

Yes, Gilbert Street is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.

Is there a guarantee on floor joint sealing in Gilbert Street?

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

How long does floor joint sealing take?

A typical job takes a few hours for most rooms, longer for large commercial floors, including preparation and clearing up. Your quote will say how long we expect yours to take.

What causes gaps between the floor and skirting?

Movement from drying timber and settling floors. Rigid fillers split, so we use a flexible sealant.

Do you use a paintable sealant?

Where the skirting will be painted, we can use a flexible sealant that takes paint. Silicone won’t take paint, so we use it where the joint stays unpainted.

What does floor joint sealing cost?

Size, access and the old material all affect the cost. Call for a quick quote and we’ll talk you through it.

Should I try DIY first?

That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.

I rent my home. Can I book you?

We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.

The process

When we arrive, we start by going over the job with you. Surfaces next to the work are protected before we start. Most jobs take a few hours, depending on the length of joint. In a small place like Gilbert Street, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  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. A flexible sealant suited to the floor is applied and tooled.
  5. Finally, we check the work and talk you through aftercare.

Before we arrive

  • Tell us about any water getting in
  • Where the joints are inside, avoid wetting them before we arrive
  • Mention any tricky access

Signs you need floor joint sealing in Gilbert Street

Caulk is the usual filler for skirting. In a joint that moves or gets wet, it splits.

Any of these means the joints need attention:

  • Threshold joints that have opened or worn
  • Failed seals where bathroom floors meet baths and panels
  • Grout cracking in a straight line across a floor
  • Skirting caulk that keeps splitting

For buildings such as Church of St Peter, floor and skirting joints in halls and kitchens wear like any others.

What your quote should include

  • Whether you can choose the colour
  • Is the old sealant removed completely?
  • Whether the sealant suits the joint
  • Who does the work, and how experienced they are

How to choose a mastic man

Can I do it myself?

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
