Need floor joint sealing in Uppend?

Floor joint sealing in Uppend

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 in a matching colour. We work on wet room & bathroom floors, skirting boards and commercial floors, and people most often call us about gaps opening between the floor and skirting and cracked caulk along skirting in bathrooms and kitchens.

Around Uppend, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.

A one-year guarantee comes with the work, just as it does everywhere we cover.

What happens if it’s left?

Caulk is quick and cheap, but it cracks where the joint moves or gets wet, so the gap reappears. A flexible sealant stretches instead. Where a wall is exposed, as many are in small places like Uppend, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

  • Colour agreed with you before any work starts
  • Sealant colour chosen to suit
  • 12-month guarantee on every job
  • Tidy, careful work

Looking after it afterwards

Joint life depends on how it’s used and looked after. We suggest:

  • Do not slide heavy items over sealed joints
  • Cone off fresh joints until they’re ready
  • Keep floor cleaning water to a minimum at the edges
  • Do not paint over silicone

Follow the cure time before walking on or cleaning the joint. Light foot traffic is usually fine sooner than wet cleaning or wheels, and we will tell you both.

Cracks along tile grout lines come back unless the movement is dealt with. Adding a movement joint early can stop cracks spreading to the tiles.

When to call us in Uppend

A new floor or screed shrinks and settles as it dries. Gaps at the edges appear in the first year or so.

Most people get in touch when they notice something like this:

  • Failed joint filler in concrete floors
  • Rigid edge joints in tiled floors
  • Floor edges that trap water and grime
  • Gaps opening between the floor and skirting

If you look after a building such as Farnham Church of England Primary School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

Questions to ask before you book

  • Whether they’re fully insured
  • What the quote includes, VAT included or not
  • How much experience the applicator has
  • What happens if the job turns out different

When something else is needed

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

  • Subfloor problems that need a flooring contractor
  • Damaged concrete that needs breaking out and repairing
  • Leaks from a failed tanking system

Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly before you book.

Surfaces we seal

What happens on the day

The work is kept neat and contained to the joints we are treating, so you can carry on as normal. The job generally takes a few hours, depending on the length of joint. In a small place like Uppend, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  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. We clean and dry the edges of the joint.
  4. A flexible sealant suited to the floor is applied and tooled.
  5. We check the joints and explain the aftercare.

How to prepare

  • Mention any tricky access
  • Keep pets and children clear of the area while we work
  • Tell us about any water getting in

Questions from Uppend

Can you help a landlord with a rental near Stansted Mountfitchet station?

Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.

Will you come out to Uppend?

Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Why not just use caulk?

Only on dry joints that don’t move. Caulk cracks as the floor moves and the gap reopens. A flexible sealant lasts longer there.

What should I tell you?

Tell us what needs doing and where, with photos by email if possible. If we need more, we’ll ask.

Can you seal over the old sealant?

No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

Are you an approved applicator?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.

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

Often, yes, at the edges and along suitable lines. We remove the grout and seal the line with flexible sealant so the floor can move.

How soon can the floor be mopped?

We will tell you before we leave. It depends on the sealant, and light foot traffic is usually fine before wet cleaning or wheels.

For landlords and businesses

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.

Should I try it myself first?

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 doesn’t work out, we can still put it right.

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.
