Floor joint sealing near Stratford

When it is not the sealant

Sealant isn’t the answer to every problem, and we’ll tell you before work begins. It will not solve:

  • Damaged concrete that needs breaking out and repairing
  • Structural movement or subsidence
  • Loose, hollow or cracked tiles, which need a tiler

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

Joints and surfaces we work on

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

Floor joint sealing in Stratford

Painted skirting can be sealed with a flexible product that can be painted over. For bathrooms and kitchens, silicone is normally the better choice, which is not made to be painted. If you have tiled floors with no room to move and threshold joints that have opened or worn, we can put it right.

From brand-new flats to converted terraces with new flooring, London has every kind of floor. Every joint between floor, skirting and threshold has to cope with some movement, in Stratford as anywhere.

There’s a 12-month guarantee on every job, whatever its size.

Floor joint sealing around Stratford

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 they don’t all move the same way. That’s why the skirting and threshold joints need a flexible seal.

Letting a property close to Stratford (London) station? Then open skirting and floor joints collect dirt and water, so seal them while the property is empty. As a London address, Stratford can be tricky for parking: let us know about parking bays, permits or a driveway.

Stratford is about 5 miles north-east of London, in Greater London. Jobs in Stratford get the same care as everywhere else we work: old sealant removed completely, careful preparation and a 12-month guarantee. Our area takes in 764 places across Greater London, large and small.

Do you need floor joint sealing in Stratford?

An open floor joint fills with dirt and water. In wet areas, water runs into the gap at every clean and behind skirting and plinths.

Common reasons people contact us include:

  • Tiled floors with no room to move
  • Caulk that has cracked where the floor moves
  • Open joints that fill with dirt
  • Gaps opening between the floor and skirting

If you look after a church, hall or community building such as Church of St John the Evangelist, floor and skirting joints in halls and kitchens wear like any others.

Questions from Stratford

Can you do floor joint sealing in Stratford?

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

Can you help a landlord with a rental near Stratford (London) station?

Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.

Will there be a smell?

Some sealants have a smell while they cure. Ventilation helps.

How long does floor joint sealing take?

It depends on the size of the job, but as a guide it takes a few hours, depending on the length of joint. We will tell you when we quote.

Do you hold any approvals?

Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.

Why not just use caulk?

Caulk can’t cope with movement or water. Skirting joints move with the floor, so a flexible sealant suits them better.

Can you quote for more than one area?

Yes. More than one area can be quoted together.

Can I do it myself?

It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.

Surface by surface

Commercial floors

Shops, offices, warehouses and units all have floor joints that need sealing. The sealant is chosen for the traffic the floor takes.

Wet room and bathroom floors

Wet room floors rely on sound joints at the walls. We reseal it with a flexible silicone suited to wet areas.

Looking after it afterwards

Aftercare is simple, and it makes a real difference:

  • Act on grout cracks that run in a straight line
  • Do not slide heavy items over sealed joints
  • Keep floor cleaning water to a minimum at the edges
  • Mark off resealed joints in warehouses

Silicone sealant is not made to take paint. If you plan to paint, we will use a paintable product.

In wet areas, an open floor joint lets water reach the subfloor. A sound seal stops that happening.

How the visit works

Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours, depending on the length of joint. In Stratford, 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. 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 smooth it.
  5. Finally, we check the work and talk you through aftercare.

Preparing for the visit

  • Tell us about any previous sealing or DIY attempts
  • Let us know about parking restrictions
  • Try not to wet indoor joints just before the visit
