Floor joint sealing in Clayhall

Floor joint sealing in Clayhall, done properly

The gap under a skirting board often opens as floors and walls move with the seasons. Decorators’ caulk generally cracks where there’s movement, so we close it with a flexible sealant instead. We work on commercial floors, wet room & bathroom floors and concrete floor joints, and people most often call us about rigid edge joints in tiled floors and failed joint filler in concrete floors.

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

You are covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or drop us an email.

How the visit works

At the end, we look at the finished work together. The work normally takes a morning or an afternoon for most homes, depending on how much there is to do. For a job in Clayhall, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. The room is cleared along the joints so we can reach them.
  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 tooled.
  5. Finally, we check the work and talk you through aftercare.

Getting ready for the visit

  • Mention any tricky access
  • Tell us about any water getting in
  • Move anything stored near the joints

Common questions in Clayhall

Do you work for landlords with property near Portsmouth Harbour station?

Yes, rental work is part of what we do. Just call 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.

Will you come out to Clayhall?

Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

What information do you need?

Where the job is, what the problem is and roughly how big it is. Photos by email help too.

Can you match the sealant colour?

Most of the time, yes. We’ll tell you which colours the right product comes in and agree one before we start.

Do you seal floor joints in bathrooms and kitchens?

Yes. These joints get wet every time the floor is cleaned, so we seal them with silicone suited to wet areas.

Is it OK to seal over 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.

Can you use decorators’ caulk instead?

Caulk works on still, dry joints, but it cracks where there’s movement or water. For most floor joints, we use a flexible sealant.

Will you leave a mess?

No. The area is protected while we work and cleaned up afterwards.

Joints and finishes in Clayhall homes

Across Hampshire, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. That’s why the skirting and threshold joints need a flexible seal.

For landlords with property near Portsmouth Harbour station, a tidy floor and skirting joint helps a rental look ready for the next tenant. Managing a site like Haselworth Primary School? Then floor and threshold joints in busy corridors wear quickly and are best resealed early. Community buildings like St Francis are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.

What sealant work cannot fix

New sealant cannot fix everything, and we’ll tell you before we start. Sealant will not put right:

  • Water getting under the tiles from elsewhere
  • Cracked or broken concrete slabs
  • Subfloor problems that need a flooring contractor

If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer.

Surfaces we seal

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

What the job involves on each surface

Commercial floors

Commercial washrooms and kitchens have floor joints that get wet constantly. They’re resealed with a flexible, water-resistant sealant.

Tiled floors

Large or heated tiled floors need room to move. Where needed, a line of grout is replaced with flexible sealant.

What affects the cost of floor joint sealing

There’s no set price list, because no two jobs are the same. What we look at:

  • The old material and how stubborn it is
  • Working hours on commercial sites
  • The type of sealant required
  • Mould in or behind the old joints

What you pay reflects the work, not a rough estimate. That is why we ask a few questions first.

Helping us quote

You do not need to know the technical terms. Just tell us:

  • The type of property
  • The address or postcode of the job
  • Any previous sealing or DIY work
  • A few pictures by email, if you can

Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we’ll come back to you with a quote.

Why deal with it now?

Regrouting a cracked line in a tiled floor rarely fixes it. If the floor needs to move there, the grout will crack again. Replacing that line with flexible sealant gives it somewhere to go. In an older home around Clayhall, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.

Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

What you get with us

  • Arbo and Everbuild products
  • Anti-fungal sanitary silicone in wet areas
  • A 12-month guarantee on all work
  • We agree the colour with you first

How to look after the new joints

To keep the joints looking good and working properly:

  • Avoid caulk in bathrooms and kitchens
  • Sweep along the edges of the floor
  • Use furniture pads near skirting
  • Check skirting joints after the heating season

Keep heavy furniture from dragging across the joints. Sharp edges can cut the sealant especially in the first few days.

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