Floor joint sealing in Iver Heath

What happens if it’s left?

Filling a skirting gap with caulk looks fine at first, but the movement soon cracks it. A flexible sealant moves with the floor. Homes in smaller places like Iver Heath can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.

Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

How we handle floor joint sealing in Iver Heath

Floors move, and the joint where they meet a wall, skirting, threshold or another floor has to move with them. Skirting-to-floor gaps, tiled floor joints and concrete joints are all sealed with a sealant suited to the movement and traffic. Typical jobs include gaps between floors and kitchen plinths and dirt and water collecting in open floor joints, on thresholds, commercial floors and concrete floor joints.

If you’ve bought a new home in or near Iver Heath, the first year or two is a good time to check the sealant. Common snags include open skirting joints, lifting shower seals and gaps around frames.

There’s a 12-month guarantee on every job, whatever its size.

Should I try it myself first?

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

FAQs for Iver Heath

Is Iver Heath in your area for floor joint sealing?

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

I let a flat near Iver station. Can you help?

Yes. We work for landlords and letting agents as well as homeowners. You can call 0345 464 0079 or email us with the details for a clear quote.

Do you work on commercial floors?

Yes. Old filler is cleaned out and the joint resealed with a floor-joint product. Tell us what runs over the floor and we will quote.

Why has a gap opened under my skirting?

Movement from drying timber and settling floors opens the gap. Caulk tends to crack; a flexible sealant does not.

Are you fully insured?

Yes. Full insurance covers our work.

What information do you need?

Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.

What does floor joint sealing cost?

It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or email us and tell us what needs doing and where.

Why not just use caulk?

Because caulk cracks where there’s movement or water. Skirting joints move with the floor, so we use a flexible sealant that stretches.

The process

Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for most rooms, longer for large commercial floors. For a job in Iver Heath, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. We start by checking the floor, the joint and what traffic it takes.
  2. We remove what’s in the joint now.
  3. We vacuum out the joint and add backing where the depth needs setting.
  4. We apply the sealant in a colour that suits the floor.
  5. We tool it neatly and tell you when it can be walked on and cleaned.

Before we arrive

  • Try not to wet indoor joints just before the visit
  • Let us know about parking restrictions
  • Tell us about any water getting in

What the job involves on each surface

Thresholds

Threshold joints get a lot of feet, so we choose a hard-wearing, flexible product and neatly finished.

Concrete floor joints

Open concrete joints chip at the edges when wheels cross them. A sealed joint protects the edges and stops debris collecting.
