Joints and finishes in Eastfields homes

Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent. Floors around Greater London run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. That is why the skirting and threshold joints need a flexible seal.

Eastfields is in London, so parking needs planning: let us know about parking bays, permits or a driveway. If you look after a church, hall or community building such as St. Mark's Church, joints in its floors, skirtings and thresholds need resealing as they wear.

About our floor joint sealing in Eastfields

Thresholds are where two floors, or a floor and a door, meet. We seal them with a flexible sealant suited to the floor finishes either side in a colour to suit. We work on commercial floors, thresholds and wet room & bathroom floors, and people most often call us about rigid edge joints in tiled floors and open gaps along the bottom of skirting boards.

Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, while new homes need a neat, sound finish around frames, baths and kitchens before handover, in Eastfields and beyond.

Whatever the size of the job, you get the same one-year guarantee in Eastfields and across Greater London.

DIY versus a professional finish

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

How to look after the new joints

So the new joints stay in good condition:

  • Avoid caulk in bathrooms and kitchens
  • Avoid sloshing water against skirting
  • Lift furniture rather than dragging it across joints
  • Mark off resealed joints in warehouses

Keep off the joint for the time we give you. Light foot traffic is generally fine sooner than wet cleaning or wheels so we will give you each time.

A gap under the skirting collects dust and lets draughts through. Sealing it keeps the room tidier and the edges sound.

The process

When we arrive, 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 any work begins. Most jobs take a few hours, depending on the length of joint. In Eastfields, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.

  1. First, the floor type, the gap and the traffic are checked.
  2. Any old caulk, grout or sealant is raked or cut out.
  3. We vacuum out the joint and add backing where the depth needs setting.
  4. We apply the sealant in a colour that suits the floor.
  5. The joint is tooled neatly and the cure time explained.

How to prepare

  • Mention any leaks or damp you’ve noticed
  • For indoor joints, keep the area dry beforehand if you can
  • Tell us about any previous sealing or DIY attempts

Related advice

Why deal with it now?

The right product depends on the floor and the traffic: flexible sealant for skirting and tiles, silicone in wet areas, and floor-joint products for concrete. Getting that choice wrong is a common reason joints fail. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Eastfields, the repair is bigger than the sealant job would have been.

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, ring 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

Why us?

  • We leave the area clean and tidy
  • Colour picked to suit the job
  • Anti-fungal silicone where joints get wet
  • Old sealant always removed completely

Read our cost guide or what customers say.

Do you need floor joint sealing in Eastfields?

An open floor joint fills with dirt and water. In wet areas, water runs into the gap at every clean and can reach the subfloor.

People usually contact us when they notice something like this:

  • Tiled floors with no room to move
  • Failed seals where bathroom floors meet baths and panels
  • Gaps at thresholds between rooms
  • Open gaps along the bottom of skirting boards

If you look after a building such as St Mark's Church of England Academy, floor and threshold joints in busy corridors wear quickly and are best resealed early.

Eastfields questions

Can you do floor joint sealing in Eastfields?

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

Can you help a landlord with a rental near Mitcham Eastfields station?

Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.

Is it messy?

Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.

Is there any odour?

Possibly a little. It fades as the sealant cures.

How do I get a quote for floor joint sealing in Eastfields?

We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.

How long will you be here?

As a guide, most jobs take a morning or an afternoon for most homes. Larger jobs naturally take longer, and we will tell you how long to expect.

Is the work guaranteed?

Yes. All our work carries our 12-month guarantee.

Will the old sealant be removed?

Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.

What affects the quote in Eastfields

For a quick quote, just ask. What matters most is:

  • When we can work, for business premises
  • Whether old sealant or filler has to be cut out
  • Whether the work is at height
  • Mould in or behind the old joints

No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

What to tell us for a quote

You do not need to know the technical terms. It helps if you can tell us:

  • The address or postcode of the job
  • The rough size of the job
  • If it’s domestic, commercial or a hotel
  • A few photos by email, if you can

To get a quote, call 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. You will have a clear quote before any work starts.

What sealant work can’t fix

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

  • Bouncy or failing floorboards
  • A tiled floor that needs relaying
  • Concrete repairs beyond the joint

If in doubt, call 0345 464 0079 or email us and we’ll say what we think before booking.
