Floor joint sealing for Lumley homes and businesses

Keeping the joints in good condition

A little care helps the new joints last. We recommend:

  • Keep floor cleaning water to a minimum at the edges
  • Keep heavy wheels off new concrete joints until cured
  • Look at floor joints each spring
  • Get cracks along tile grout lines looked at early

Mop with a well-wrung mop rather than flooding the floor. Keeping the edges drier helps the sealant last longer.

Water getting into floor joints in bathrooms and kitchens can damage what’s underneath. Resealing early keeps it out.

Floor joint sealing in Lumley, done properly

Large tiled floors, and those over underfloor heating, often need movement joints. Where one is needed, we rake out the grout along the right line and replace it with flexible sealant coloured to suit the grout. Common call-outs are for skirting caulk that keeps splitting and gaps opening between the floor and skirting, across wet room & bathroom floors, commercial floors and thresholds.

For a small place like Lumley, the journey and access are planned in advance, and the work itself is the same as on any site.

We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

What happens if it’s left?

Leaving skirting gaps until the next decorating job lets dirt and draughts in. Sealing them now is a short job for most homes. Around Lumley, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

The cost depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.

Why book with us

  • Sealant colour chosen to suit

Can I do it myself?

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

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Quotes for floor joint sealing in Lumley

Every job gets its own quote. These are the things that affect it:

  • The size of the job
  • Any working-time requirements on site
  • How easy the joints are to reach
  • The number of rooms or windows

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

What to tell us for a quote

To help us quote quickly, let us know:

  • Whether it has been sealed before
  • How many joints, rooms or windows are involved
  • What the problem is, such as mould, gaps, leaks or cracking
  • Where the job is, and your postcode

Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we’ll talk you through the work.

What we do, step by step

When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a morning or an afternoon for most homes. For a village or hamlet like Lumley, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  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. We apply a flexible sealant suited to the floor and smooth it.
  5. Finally, we check the work and talk you through aftercare.

Getting ready for the visit

  • Tell us about access, such as stairs, a lift or high-level joints
  • Keep children and pets away from the work area
  • Try not to wet indoor joints just before the visit

Advice

Landlord and commercial work in Lumley

In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can go on one quote.

What we’re called out for in Lumley

Floors and walls move a little with the seasons. In winter, with the heating on, timber dries and gaps open and they change again in summer.

Signs it’s time to call us include:

  • Skirting that has pulled away from the floor
  • Chipped and open joints in warehouse floors
  • Dirt and water collecting in open floor joints
  • Caulk that has cracked where the floor moves

Managing a site like St James Church of England Controlled Primary School? Then entrance and corridor floor joints take a lot of traffic.

What to look for in a quote

  • Whether VAT is included
  • What guarantee comes with the work
  • Whether you can choose the colour
  • Which sealant they’ll use, and why

Our hiring checklist

Floor joint sealing around Lumley

Across West Sussex, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.

For landlords with property near Emsworth station, open skirting and floor joints collect dirt and water, so seal them while the property is empty. If you look after a church, hall or community building such as Church of St James, floor and skirting joints in halls and kitchens wear like any others.

Lumley questions

Is Lumley within the area you cover?

Yes, Lumley is covered. 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 Lumley for floor joint sealing?

Yes. Our work covers London and the South East, and Lumley is part of that. Just call 0345 464 0079 or send us an email with a few details of the job.

Can grout be replaced with sealant on a tiled floor?

Often, yes, where it suits the floor. The grout is raked out and replaced with a flexible sealant in a colour to suit, giving the floor room to move.

What information do you need?

Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.

Are you fully insured?

Yes. We’re fully insured, and we can confirm the details when we quote.

Will there be a smell?

That depends on the sealant. Some smell for a while, some hardly at all.

Is it worth trying it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Do you remove the old sealant?

Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
