How to look after the new joints

Simple care keeps the joints in good condition. Our advice:

  • Do not paint over silicone
  • Lift furniture rather than dragging it across joints
  • Have a cracking tiled floor checked before tiles break
  • Avoid caulk in bathrooms and kitchens

Keep off the joint for the time we give you. Feet are generally fine before mopping or wheeled traffic.

Open skirting gaps let in draughts, dust and sometimes insects. Sealing it keeps the room tidier and stops it getting worse.

About our floor joint sealing in Colney Butts

Floor joint sealing is mostly about choosing the right product and preparing the joint. Old caulk, grout or failed sealant comes out first, the joint is cleaned and backed where needed, then the new sealant goes in. If you have failed seals where bathroom floors meet baths and panels and perimeter joints in tiled floors filled with grout, we can help, whatever the surface.

If you’ve bought a new home in or near Colney Butts, the first year or two is a good time to check the sealant. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.

A 12-month guarantee comes with the work, just as it does everywhere we cover.

Do you need floor joint sealing in Colney Butts?

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, where a flexible joint should have been.

Signs it’s time to call us include:

  • Caulk that has cracked where the floor moves
  • Skirting that has pulled away from the floor
  • Concrete floor joints that have broken down
  • Grout used at the floor edge instead of sealant

Managing a site like Watford Grammar School for Girls? Then floor and threshold joints in busy corridors wear quickly and are best resealed early.

10 questions to ask before you book

Why deal with it now?

Left open, concrete joints break down under traffic. Resealing it early protects the edges. In an older home around Colney Butts, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.

What floor joint sealing looks like in Colney Butts

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

For landlords with property near Watford High Street station, gaps at skirtings and thresholds are worth sealing between tenancies. For buildings such as St Mary's Church, joints in its floors, skirtings and thresholds need resealing as they wear.

FAQs for Colney Butts

Will you come out to Colney Butts?

Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Do you cover Colney Butts for floor joint sealing?

Yes, Colney Butts is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we will send you a clear quote.

Are you an approved applicator?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.

What causes gaps between the floor and skirting?

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

My floor grout keeps cracking in a line. Can you help?

Often, yes. Where a floor needs one, we rake out grout along the right line and replace it with flexible sealant. Loose or cracked tiles need a tiler first.

What sealant do you use?

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

Do you take out the old sealant first?

Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.

When can I walk on the floor?

That varies with the sealant and the room. We give you the times for walking, cleaning and traffic when we finish so you can plan.

Surface by surface

Concrete floor joints

We clean concrete joints out thoroughly before sealing, vacuuming them clean. Backing goes in where the depth needs controlling.

Wet room and bathroom floors

Floor joints in bathrooms take water every day. They’re sealed with a flexible, anti-fungal silicone that keeps water out.

DIY sealant or a professional job?

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

What we can’t put right

New sealant can’t fix everything, and we’d rather say so up front. It will not solve:

  • Structural movement or subsidence
  • A tiled floor that needs relaying
  • Water getting under the tiles from elsewhere

If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before you book.

What we seal

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

How it works

We bring everything the job needs with us. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours for most rooms, longer for large commercial floors. In a smaller place like Colney Butts, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.

  1. We clear the edges of the floor so the joints are easy to reach.
  2. Old material is removed from the joint.
  3. We clean and dry the edges of the joint.
  4. We apply a flexible sealant suited to the floor and smooth it.
  5. We check the joints and explain the aftercare.

How to prepare

  • Clear the area around the work
  • Where the joints are inside, avoid wetting them before we arrive
  • Mention any tricky access
