Floor joint sealing near Brighton and Hove

The process

All our tools and materials come with us in the van. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours, depending on the length of joint. In Brighton and Hove, parking is rarely complicated, though it helps to know about driveways or restrictions, and let us know if the work is upstairs, in a flat or up high outside.

  1. We look at the gap and the floor type and agree the right sealant.
  2. Old caulk, grout or sealant is removed from the joint.
  3. We clean and vacuum the joint and fit backing where the depth needs setting.
  4. A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
  5. The joint is tooled to a neat finish and we tell you when it can take feet and a mop.

Preparing for the visit

  • Move anything stored near the joints
  • Where the joints are inside, avoid wetting them before we arrive
  • Tell us about any previous sealing or DIY attempts

How we handle floor joint sealing in Brighton and Hove

Tiled floors can crack along the grout when there’s no room for movement. Where one is needed, we rake out the grout along the right line and replace it with flexible sealant. If you have open joints that fill with dirt and worn sealant at door thresholds, we can help.

In a town like Brighton and Hove, older houses sit alongside newer estates. In a newer home, sealant and floor joints are generally among the first things to need attention.

We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Why it’s worth doing now in Brighton and Hove

Not every floor joint takes the same sealant: skirting and tiled floors need flexibility, wet areas need water resistance and concrete needs a product suited to wheels. Getting that choice wrong is a common reason joints fail. In Brighton and Hove, as anywhere, most leaks start as a small gap in a joint, and they’re far easier to fix early.

No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.

What you get with us

  • 4.9 on Google from 180+ five-star reviews
  • We leave the area clean and tidy
  • Old sealant always removed completely
  • A 12-month guarantee on all work

Joints and finishes in Brighton and Hove homes

Across Brighton and Hove, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.

If you let a flat or house near Aldrington station, gaps at skirtings and thresholds are worth sealing between tenancies. If you look after a building such as West Hove Infant School, floor and threshold joints in busy corridors wear quickly and are best resealed early. Community buildings like Holy Cross Church are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.

For landlords and businesses

For anyone letting property in or around Brighton and Hove, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs.

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

Should I try it myself first?

If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What we can’t put right

  • Leaks from a failed tanking system
  • Tiles that have lifted or broken
  • Floors that are uneven or need levelling

How we quote for floor joint sealing

For a quick quote, just ask. What matters most is:

  • How easy the joints are to reach

A few things move the cost up or down: 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.

Different surfaces, different methods

Wet room and bathroom floors

Wet room floors rely on sound joints at the walls. We reseal it with a flexible silicone suited to wet areas and we’ll say if the problem looks like more than the joint.

Commercial floors

Washroom and kitchen floors in commercial buildings need sound edge joints. We reseal them with a sealant suited to wet areas.

Brighton and Hove questions

Is there a guarantee on floor joint sealing in Brighton and Hove?

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

Do you cover Brighton and Hove for floor joint sealing?

Yes, Brighton and Hove is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and let us know what needs doing.

Are you ARBOMaster approved?

Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.

Is it messy?

We keep the work tidy. We protect what’s around the joints, and we clear up when we are done.

Can grout be replaced with sealant on a tiled floor?

Often, yes, at the edges and along suitable lines. We remove the grout and seal the line with flexible sealant, giving the floor room to move.

Can you seal over the old sealant?

No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.

Why has a gap opened under my skirting?

Floors shrink and settle, especially in the first year or two and through the heating season pulls the skirting and floor apart. Rigid fillers split, so we use a flexible sealant.

How long before the joint can take traffic?

Follow the cure time we give you. Light use comes first, cleaning and heavy traffic later, depending on the product.
