Floor joint sealing in Stanmore

Stanmore: your questions answered

Can you do floor joint sealing in Stanmore?

Yes, Stanmore is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.

Do you work for landlords with property near Winchester station?

Yes. We work for landlords and agents as well as homeowners. You can ring 0345 464 0079 or email us with the details for a clear quote.

Can I do it myself?

Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Can you seal over the old sealant?

No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.

Are you fully insured?

Yes. We’re fully insured, with over 20 years’ experience in sealant work.

Why has a gap opened under my skirting?

Floors shrink and settle, especially in the first year or two and through the heating season. Caulk tends to crack; a flexible sealant does not.

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

Often, yes. Straight cracks in grout often show where a movement joint was needed. We replace that grout with a flexible joint.

Can sealant along the skirting be painted?

It depends on the sealant, so let us know first. We use a paintable flexible sealant on joints you plan to paint, and silicone elsewhere.

About our floor joint sealing in Stanmore

A threshold joint has to cope with feet, movement and sometimes water. We use a flexible product that suits both floors so the joint stays neat. We work on thresholds, concrete floor joints and wet room & bathroom floors, and people most often call us about concrete floor joints that have broken down and perimeter joints in tiled floors filled with grout.

Where new homes go up in smaller places like Stanmore, it’s often a small development or a single plot. Each still needs its sealant and floor joints finished properly from day one.

All of our work is guaranteed for twelve months.

How we quote for floor joint sealing

There’s no set price list. What we look at:

  • The number and length of the joints
  • Any working-time requirements on site
  • How much old sealant there is and how hard it is to remove
  • Mould in or behind the old joints

What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before work begins.

Helping us quote

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

  • Roughly how big the job is
  • Where the job is, and your postcode
  • The type of property
  • Any access issues, like height or stairs

Asking for a quote is easy: let us know what needs doing and where. Photos by email help us understand the job, and we’ll come back to you with a quote.

Signs you need floor joint sealing in Stanmore

Wheels crossing an unfilled concrete joint chip its edges. Hard wheels damage the joint edges.

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

  • Gaps at thresholds between rooms
  • Skirting caulk that keeps splitting
  • Grout cracking in a straight line across a floor
  • Gaps between floors and kitchen plinths

If you look after a building such as Stanmore Primary School, floor and threshold joints in busy corridors wear quickly and are best resealed early.

Questions to ask before you book

  • Whether you can choose the colour
  • What insurance they hold
  • Whether the sealant suits the joint
  • What the cure time is

10 questions to ask before booking

Work for landlords, hotels and businesses

Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.

How the job changes by surface

Tiled floors

A crack running along a grout line is often a sign of a missing movement joint. That line is converted to a flexible joint.

Commercial floors

Commercial floors take more traffic than most homes. We talk through the traffic and choose a sealant suited to it.

How it works

On the day, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before work begins. Most jobs take a few hours, depending on the length of joint. Parking around Stanmore is usually 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. 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. Edges are cleaned and dried.
  4. A flexible sealant suited to the floor is applied and tooled.
  5. We check the joints and explain the aftercare.

Preparing for the visit

  • Mention if the joints have been sealed before
  • Keep children and pets away from the work area
  • Mention any tricky access

New homes and floors in Stanmore

Floors around Hampshire run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.

For buildings such as Saint Luke, floor and skirting joints in halls and kitchens wear like any others. If you let a flat or house near Winchester station, a tidy floor and skirting joint helps a rental look ready for the next tenant.

When something else is needed

Honest advice matters more to us than a booking, so here’s what new sealant will not do:

  • Concrete repairs beyond the joint
  • Loose, hollow or cracked tiles, which need a tiler
  • Large cracks that need a surveyor

If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.

What we seal

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

DIY versus a professional finish

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.

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.
