Floor joint sealing for Brighton homes and businesses

How we handle floor joint sealing in Brighton

In commercial and industrial units, concrete floor joints take a hammering from wheels and traffic. Each is resealed with a floor-joint product suited to what runs over it. If you’re dealing with grout cracking in a straight line across a floor and perimeter joints in tiled floors filled with grout, we can put it right, whatever the surface.

Commercial units around a large town like Brighton usually have concrete floors with joints that need filling and resealing as they wear. Homes need the same attention on a smaller scale, from skirting joints to shower seals.

Our work is backed for twelve months, in Brighton and everywhere else we cover.

Different surfaces, different methods

Thresholds

Where a tiled floor meets timber or carpet, the joint takes movement from both sides. A flexible sealant bridges them.

Tiled floors

When grout cracks along a straight line, the floor is telling you it needs to move. That line is converted to a flexible joint where it suits the floor.

Honest limits

To be straight with you, some problems need a different trade:

  • Failed waterproofing under a wet room floor
  • Damaged concrete that needs breaking out and repairing
  • Tiles that have lifted or broken

If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.

What we seal

  • Commercial floors
  • Tiled floors
  • Skirting boards
  • Wet room & bathroom floors
  • Thresholds
  • Concrete floor joints

Should I try it myself first?

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

What happens on the day

We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours, depending on the length of joint. For homes and businesses in busier parts of Brighton, parking needs a little planning. Let us know about stairs, lifts or shared entrances too.

  1. We clear the edges of the floor so the joints are easy to reach.
  2. We take out the cracked caulk, grout or old sealant.
  3. We clean and dry the edges of the joint.
  4. We apply a flexible sealant suited to the floor.
  5. We check the joints and explain the aftercare.

Before we arrive

  • Clear the area around the work
  • Mention any parking rules near the property
  • Keep children and pets away from the work area

Advice

When to call us in Brighton

Floors and walls move a little with the seasons. In winter, with the heating on, timber dries and gaps open and they change again in summer.

These are the problems we’re asked about most:

  • Perimeter joints in tiled floors filled with grout
  • Gaps between floors and kitchen plinths
  • Threshold joints that have opened or worn
  • Floor edges that trap water and grime

For buildings such as St Martin's Church, joints in its floors, skirtings and thresholds need resealing as they wear.

What your quote should include

  • How hidden problems are handled
  • Whether they seal over old material or remove it
  • Who turns up on the day
  • The length of the guarantee

Choosing a sealant specialist

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. Getting that choice wrong is a common reason joints fail. For businesses in Brighton, a room closed because of a leak or mould costs more than the sealant, so failing joints are best replaced on a planned basis.

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we will go through it with you.

Why book with us

  • Old sealant always removed completely
  • Anti-fungal sanitary silicone in wet areas
  • Fully insured
  • We agree the colour with you first

Brighton questions

Is floor joint sealing in Brighton guaranteed?

Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.

Why has a gap opened under my skirting?

Floors and walls move a little with the seasons, and new floors settle. A flexible sealant closes the gap without cracking like caulk.

We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.

For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
