How we handle floor joint sealing in Keyhaven

Gaps along the bottom of skirting are common in new and older homes alike. Decorators’ caulk normally cracks where there’s movement, so we close it with a flexible sealant instead. Common call-outs are for failed seals where bathroom floors meet baths and panels and threshold joints that have opened or worn, on concrete floor joints, skirting boards and wet room & bathroom floors.

Around Keyhaven, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.

There’s a 12-month guarantee on every job, large or small.

Can I do it myself?

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

Aftercare tips

Good habits help new joints last longer. A few tips:

  • Lift furniture rather than dragging it across joints
  • Mark off resealed joints in warehouses
  • Keep dirt out of the joints
  • Look at floor joints each spring

Keep heavy traffic off resealed concrete joints for the cure time we give you. Cone off the area if needed while it cures.

A tiled floor that cracks along a line will keep cracking until it can move. A flexible joint added early helps protect the tiles themselves.

Honest limits

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

  • Movement too big for a sealant joint
  • Failed waterproofing under a wet room floor
  • Cracked or broken concrete slabs

Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.

Joints and surfaces we work on

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

Why it’s worth doing now in Keyhaven

Open joints along wet floors let water into the subfloor and behind skirting. Dealing with it early keeps the repair to the joint. Where a wall is exposed, as many are in small places like Keyhaven, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Doing several joints on one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

Why book with us

  • Colour picked to suit the job
  • Trusted Arbo and Everbuild sealants
  • Anti-fungal sanitary silicone in wet areas
  • We leave the area clean and tidy

Do you need floor joint sealing in Keyhaven?

Grout is rigid, so a tiled floor with nowhere to move cracks along a grout line. Cracks often run straight along a line of joints, showing where a movement joint was needed.

It’s worth asking for a quote if you see:

  • Perimeter joints in tiled floors filled with grout
  • Gaps between floors and kitchen plinths
  • Cracked caulk along skirting in bathrooms and kitchens
  • Open joints that fill with dirt

Community buildings like Church of All Saints are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.

Floor joint sealing in Keyhaven: local notes

Across Hampshire, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they don’t all move the same way. That is why the skirting and threshold joints need a flexible seal.

Rented homes near Lymington Town station change hands often, and a tidy floor and skirting joint helps a rental look ready for the next tenant. Schools such as Milford-on-Sea Church of England Primary School are buildings too, and floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

How it works

Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a morning or an afternoon for most homes. Somewhere as small as Keyhaven, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. First we check the joint and the floor and agree which sealant suits it.
  2. Whatever is in the joint now, whether caulk, grout or sealant, comes out.
  3. The joint is vacuumed clean, with backing fitted wherever depth matters.
  4. The sealant goes in, chosen for the floor and coloured to suit it.
  5. Finally we tool it smooth and explain when the floor can be used and cleaned.

Preparing for the visit

  • Plan for the work area to be out of bounds to pets and children
  • Tell us about access, such as stairs, a lift or high-level joints
  • Tell us about any water getting in
