About our floor joint sealing in Dedworth

Good floor joints come down to the right product and clean, prepared edges. Old caulk, grout or failed sealant comes out first, then clean, back and seal the joint. Common call-outs are for chipped and open joints in warehouse floors and perimeter joints in tiled floors filled with grout, on commercial floors, wet room & bathroom floors and thresholds.

In smaller places like Dedworth, new homes tend to come as small developments or single plots. Each still needs its sealant and floor joints finished properly from day one.

Each job carries a 12-month guarantee, large or small.

DIY sealant or a professional job?

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

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.

Common problems we fix in Dedworth

Concrete floor joints break down when traffic runs over open or failed joints. Hard wheels damage the joint edges until the joint widens.

The most common problems we see are:

  • Rigid edge joints in tiled floors
  • Cracked grout where a tiled floor needs a movement joint
  • Gaps at thresholds between rooms
  • Gaps opening between the floor and skirting

Rented homes near Windsor & Eton Central station change hands often, and a tidy floor and skirting joint helps a rental look ready for the next tenant.

10 questions to ask before you book

Common questions in Dedworth

I let a flat near Windsor & Eton Central station. Can you help?

Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or send us an email with the details for a clear quote.

Will you come out to Dedworth?

Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Do I have to be there?

It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.

What should I tell you?

The location, the problem and the rough size of the job. Photos by email help too.

Do you seal kitchen plinths to the floor?

Yes. Where a floor meets a bath panel, kitchen plinth or skirting in a wet area, we use a flexible silicone so water can’t get into the gap.

Can new sealant go over the old?

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.

Will the old sealant be removed?

Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

Which products do you use?

It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

Floor joint sealing around Dedworth

Floors around Windsor and Maidenhead run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. That’s why the skirting and threshold joints need a flexible seal.

If you look after a building such as Dedworth Green First School, floor and threshold joints in busy corridors wear quickly and are best resealed early. Community buildings like All Saints Church are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.

Why act early in Dedworth

Dirt builds up in open joints, and they look untidy. A neat sealed joint is easier to clean and finishes the floor. Homes in smaller places like Dedworth can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.

Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

What you get with us

  • 20+ years of sealant experience
  • 4.9 on Google from 180+ five-star reviews
  • Anti-fungal silicone where joints get wet
  • Trusted Arbo and Everbuild sealants

Quotes for floor joint sealing in Dedworth

The price is agreed before any work begins. It’s based on:

  • Whether old sealant or filler has to be cut out
  • The number of rooms or windows
  • The product the joint needs
  • Mould in or behind the old joints

Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or send us an email and we will give you an honest view and a quote.

What we need to know

Photos by email are helpful but not essential. Please mention:

  • What’s wrong with the joints now
  • The type of property
  • If someone has resealed it before
  • Photos by email, if that is easy

There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or send us an email.

What happens on the day

On the day, we start by going over the job with you, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for most rooms, longer for large commercial floors. Parking around Dedworth is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.

  1. The room is cleared along the joints so we can reach them.
  2. We take out the cracked caulk, grout or old sealant.
  3. Edges are cleaned and dried.
  4. We apply a flexible sealant suited to the floor and tooled.
  5. Finally, we check the work and talk you through aftercare.

How to prepare

  • Keep pets and children clear of the area while we work
  • Clear items away from the joints we are working on
  • Mention any parking rules near the property

Advice

What the job involves on each surface

Old filler, dust and debris are cleaned out of the joint, vacuuming them clean. We fit backing where needed.

What sealant work can’t fix

Some problems need a builder, plumber or other trade rather than us:

  • A tiled floor that needs relaying
  • Subfloor problems that need a flooring contractor
