Trusted floor joint sealing in Freemantle

The process

All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes a morning or an afternoon for most homes. Parking around Freemantle is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.

  1. First, the floor type, the gap and the traffic are checked.
  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. The joint is tooled neatly and the cure time explained.

How to prepare

  • Tell us if parking is tricky
  • Move anything stored near the joints
  • Where the joints are inside, avoid wetting them before we arrive

Floor joint sealing for homes and businesses in Freemantle

We seal floor joints in homes, offices and commercial buildings across Freemantle. We start by checking the floor type and the joint, because the right sealant depends on both. We work on commercial floors, tiled floors and wet room & bathroom floors, and people most often call us about gaps between floors and kitchen plinths and open gaps along the bottom of skirting boards.

Where new homes go up in smaller places like Freemantle, it’s often a small development or a single plot. Each still needs its sealant and floor joints finished properly from day one.

A 12-month guarantee comes as standard.

Your questions about floor joint sealing in Freemantle

Can you do floor joint sealing in Freemantle?

Yes. We work across London and the South East, and Freemantle is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing.

Do you work for landlords with property near Millbrook (Hants) station?

Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.

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.

Do the sealants smell?

Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.

Will it make a mess?

Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.

Can you seal over the old sealant?

No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.

Where are you based?

Our base is Crawley. We work across South East England, London and Scotland.

Will the old sealant be removed?

Yes. All of the old material is cut out and the joint cleaned.

How we quote for floor joint sealing

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • The product the joint needs

  • If it’s domestic, commercial or a hotel
  • How we’d reach the joints
  • The problem you’ve noticed
  • Pictures of the joints, sent by email

Do you need floor joint sealing in Freemantle?

A new floor or screed shrinks and settles as it dries. The edges pull away from the skirting.

The problems people normally mention when they call are:

  • Skirting caulk that keeps splitting
  • Open joints around bathroom floor edges
  • Gaps opening between the floor and skirting
  • Concrete floor joints that have broken down

Rented homes near Millbrook (Hants) station change hands often, and a tidy floor and skirting joint helps a rental look ready for the next tenant.

What to look for in a quote

  • Are they insured?
  • How the surfaces are prepared before sealing
  • What happens if they find a problem under the old sealant
  • Is the old sealant removed completely?

10 questions to ask before you book

DIY sealant or a professional job?

The difference is mostly in the preparation and the 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.

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.

For landlords and businesses

Landlords and letting agents in Freemantle can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.

What floor joint sealing looks like in Freemantle

Across Southampton, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. That’s why the skirting and threshold joints need a flexible seal.

If you look after a church, hall or community building such as Christ Church, joints in its floors, skirtings and thresholds need resealing as they wear. Schools such as Freemantle Church of England Community Academy are buildings too, and floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

Different surfaces, different methods

Thresholds

Thresholds between rooms meet two floors and often a door frame. A flexible sealant suits both floor finishes.

Commercial floors

Commercial floors take more traffic than most homes. The sealant is chosen for the traffic the floor takes.

When something else is needed

Before you book, it’s worth knowing the limits:

  • Bouncy or failing floorboards
  • Movement too big for a sealant joint
  • Water getting under the tiles from elsewhere

Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before you book.
