Floor joint sealing in Cobham, done properly

Where skirting is painted, we can use a flexible sealant that takes paint. In wet areas we’d normally use silicone. We work on skirting boards, thresholds and tiled floors, and common reasons people get in touch are grout used at the floor edge instead of sealant and open gaps along the bottom of skirting boards.

Older homes in small places like Cobham often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.

Your job is guaranteed for a year, as with all our work.

What happens if it’s left?

Open joints along wet floors let water into the subfloor and behind skirting. Sealing them now keeps the problem at the surface. Around Cobham, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

How we quote for floor joint sealing

The price is agreed before any work begins. It takes into account:

  • The number of rooms or windows
  • The amount of work
  • Mould in or behind the old joints
  • How much old sealant there is and how hard it is to remove

Doing several joints on one visit generally makes better use of the time than several visits. You will get one clear quote for the whole job.

What to tell us for a quote

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

  • What’s wrong with the joints now
  • Any previous sealing or DIY work
  • Whether it’s a home or a business
  • Any access issues, like height or stairs

Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand, and we will take it from there.

The process

Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours, depending on the length of joint, and the area is left clean. Somewhere like Cobham needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. We start by checking the floor, the joint and what traffic it takes.
  2. We remove what’s in the joint now.
  3. The joint is vacuumed clean and backing fitted where needed.
  4. The chosen sealant goes in, coloured to suit the floor.
  5. The joint is tooled neatly and the cure time explained.

Getting ready for the visit

  • Let us know about earlier repairs to the joints
  • Keep pets and children clear of the area while we work
  • Mention any tricky access

Related advice

For landlords and businesses

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.

DIY sealant or a professional job?

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

Do you need floor joint sealing in Cobham?

A new floor or screed shrinks and settles as it dries. Gaps at the edges appear in the first year or so and anything rigid cracks.

The problems people generally mention when they call include:

  • Skirting caulk that keeps splitting
  • Perimeter joints in tiled floors filled with grout
  • Open gaps along the bottom of skirting boards
  • Cracked grout where a tiled floor needs a movement joint

Managing a site like Cobham Primary School? Then entrance and corridor floor joints take a lot of traffic.

What to look for in a quote

  • Who does the work, and how experienced they are
  • What product goes in the joint
  • Whether they’re fully insured
  • How the surfaces are prepared before sealing

10 questions to ask before booking

Cobham questions

Do you cover smaller places like Cobham?

Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Is Cobham in your area for floor joint sealing?

Yes, Cobham 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 send you a clear quote.

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, and we’ll explain our choice.

Will I be able to paint over the new joint?

If you tell us beforehand, yes. Joints that will be painted get a paintable product and wet areas get silicone.

How long will you be here?

As a guide, most jobs take a few hours, depending on the length of joint. Bigger jobs take longer, and we will say how long yours will take.

Do you work on commercial floors?

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

I’m a tenant. Can you help?

Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.

Do the sealants smell?

Possibly a little. Any smell clears as the sealant cures, and ventilation helps.

Different surfaces, different methods

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.

Concrete floor joints

Sawn joints in concrete floors control where it cracks. We reseal them with a floor-joint product suited to the traffic.

Joints and finishes in Cobham homes

Across Kent, 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 buildings such as Parish Church of St Mary Magdalene, floor and skirting joints in halls and kitchens wear like any others. If you let a flat or house near Sole Street station, open skirting and floor joints collect dirt and water, so seal them while the property is empty.
