Floor joint sealing for Gun Hill homes and businesses

How we handle floor joint sealing in Gun Hill

In kitchens and bathrooms, the joint where the floor meets a bath panel, plinth or skirting takes mop water every day. A flexible silicone seal keeps it out so water and dirt can’t get in. We work on commercial floors, concrete floor joints and skirting boards, and common reasons people get in touch are worn sealant at door thresholds and dirt and water collecting in open floor joints.

Work in a small place like Gun Hill just needs the journey and access planning, and once on site, the job is the same as anywhere.

You are covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Should I try it myself first?

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.

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Quotes for floor joint sealing in Gun Hill

The price is agreed before any work begins. It’s based on:

  • How much there is to do
  • Whether the work is at height
  • How many rooms, windows or areas are involved
  • How much old sealant there is and how hard it is to remove

Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we’ll explain what it covers.

What to tell us for a quote

A few details help us give you an accurate quote. When you get in contact, it helps to mention:

  • Photos by email, if that is easy
  • If it’s domestic, commercial or a hotel
  • The problem you’ve noticed
  • How many joints, rooms or windows are involved

It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. Whenever you are ready, phone 0345 464 0079 or drop us an email.

Do you need floor joint sealing in Gun Hill?

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.

It’s worth asking for a quote if you see:

  • Failed seals where bathroom floors meet baths and panels
  • Rigid edge joints in tiled floors
  • Skirting that has pulled away from the floor
  • Skirting caulk that keeps splitting

For jobs in and around Gun Hill, choosing the right material for each joint is as important as a tidy finish.

10 questions to ask before you book

Your questions about floor joint sealing in Gun Hill

Do you cover smaller places like Gun Hill?

Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Is there a guarantee on floor joint sealing in Gun Hill?

All our work, in Gun Hill and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.

Can you seal over the old sealant?

No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.

Can sealant along the skirting be painted?

It depends on the sealant, so let us know first. We use a paintable flexible sealant on joints you plan to paint, and silicone elsewhere.

Why has a gap opened under my skirting?

Floors and walls move a little with the seasons, and new floors settle. We close it with a flexible sealant that moves with the floor.

How long before the joint can take traffic?

We’ll tell you before we leave. That depends on the product, and light foot traffic is usually fine before wet cleaning or wheels.

Do the sealants smell?

It depends on the product. Some products have a noticeable smell, others very little.

Can you reseal concrete floor joints in an industrial unit?

Yes. We clean out the joints and reseal them with a product suited to the floor. Tell us what runs over the floor when you ask for a quote.

New homes and floors in Gun Hill

Across East Sussex, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they do not all move the same way. The joint at the skirting or threshold has to allow for that.

In and around Gun Hill, as anywhere, good floor joint sealing starts with a clean, dry, properly prepared joint.

How the job changes by surface

Tiled floors

When grout cracks along a straight line, the floor is telling you it needs to move. We rake out that line and seal it where it suits the floor.

Concrete floor joints

Sawn joints in concrete floors control where it cracks. We reseal them with a floor-joint product suited to the traffic.

Why act early in Gun Hill

Regrouting a cracked line in a tiled floor rarely fixes it. The movement is still there, so the grout fails again. A flexible movement joint is the fix. In a small place like Gun Hill, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

The cost reflects the work involved, not a rough estimate. That is why we ask about the job first.

Why Gun Hill clients choose us

  • We’re fully insured
  • ARBOMaster approved applicator
  • Trusted Arbo and Everbuild sealants
  • Any old sealant cut out fully, not covered over

Take a look at our cost guide or customer reviews.

When it is not the sealant

Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:

  • A tiled floor that needs relaying
  • Subfloor problems that need a flooring contractor
  • Leaks from a failed tanking system

Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly.

Surfaces we seal

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

How it works

On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes a morning or an afternoon for most homes, including the tidy-up. For a village or hamlet like Gun Hill, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. First, the floor type, the gap and the traffic are checked.
  2. We remove what’s in the joint now.
  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.

Getting ready for the visit

  • Mention any tricky access
  • Tell us if parking is tricky
  • Mention any leaks or damp you’ve noticed
