Floor joint sealing near Blenheim

Keeping the joints in good condition

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

  • Get cracks along tile grout lines looked at early
  • Keep floor cleaning water to a minimum at the edges
  • Look at floor joints each spring
  • Avoid caulk in bathrooms and kitchens

Keep heavy traffic off resealed concrete joints for the cure time we give you. Mark the area off so drivers avoid it.

Water getting into floor joints in bathrooms and kitchens can damage what’s underneath. A sound seal stops that happening.

About our floor joint sealing in Blenheim

Across Blenheim, we seal floor and skirting joints in homes and businesses. Each job starts with looking at the floor and the gap, since that decides which sealant suits. We work on tiled floors, thresholds and commercial floors, and people most often call us about dirt and water collecting in open floor joints and cracked grout where a tiled floor needs a movement joint.

Work in a small place like Blenheim just needs the journey and access planning, and the work itself is the same as on any site.

You get a 12-month guarantee, the same in Blenheim as everywhere else we work.

How the visit works

At the end, we look at the finished work together. The visit itself usually takes a morning or an afternoon for most homes, depending on the size of the job. In a small place like Blenheim, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First we check the joint and the floor and agree which sealant suits it.
  2. We take out any old caulk, sealant or grout along the line.
  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

  • Mention any tricky access
  • Where the joints are inside, avoid wetting them before we arrive
  • Let us know if you’ve seen damp or leaks

Advice

Questions from Blenheim

Do you cover smaller places like Blenheim?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Is Blenheim in your area for floor joint sealing?

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

Is there any odour?

Sometimes, a little. It fades as the sealant cures.

Can you use decorators’ caulk instead?

Caulk cannot cope with movement or water. Floor edges move through the year, so we use a flexible sealant that stretches.

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, and we will explain our choice.

Can sealant along the skirting be painted?

If you tell us beforehand, yes. Joints that will be painted get a paintable product.

Do you seal floor joints in bathrooms and kitchens?

Yes. Wet-area floor joints are sealed with a flexible, water-resistant silicone so water can’t get into the gap.

Is it messy?

Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.

What affects the cost of floor joint sealing

Your quote is based on your job. We look at:

  • How easy the joints are to reach
  • Mould in or behind the old joints
  • The amount of work
  • The type of sealant required

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

Asking for a quote

Before you ask for a quote, have a think about:

  • Whether it’s a home or a business
  • Photos by email, if that’s easy
  • Where the job is, and your postcode
  • Roughly how big the job is

Asking for a quote is easy: let us know the job and the location and its rough size. Photos by email help us understand the job, and we will come back to you with a quote.

When it is not the sealant

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

  • Damaged concrete that needs breaking out and repairing
  • A tiled floor that needs relaying
  • Movement too big for a sealant joint

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

Surfaces we seal

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

DIY sealant or a professional job?

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

Landlords, agents and businesses in Blenheim

Landlords and letting agents in Blenheim can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.

What the job involves on each surface

Wet room and bathroom floors

Floor joints in bathrooms take water every day. We seal them with anti-fungal sanitary silicone that keeps water out.

Thresholds

A threshold is where floors and frames meet. We seal them with a flexible sealant that suits both sides.

What floor joint sealing looks like in Blenheim

Floors around Oxfordshire run from suspended timber in older homes to concrete in newer houses and units, and they don’t all move the same way. The joint at the skirting or threshold has to allow for that.

For buildings such as Church of St Mary, floor and skirting joints in halls and kitchens wear like any others. Managing a site like Garsington Church of England Primary School? Then entrance and corridor floor joints take a lot of traffic. If you let a flat or house near Radley station, open skirting and floor joints collect dirt and water, so seal them while the property is empty.
