Need floor joint sealing in South Harting?

Floor joint sealing in South Harting

Floor joint sealing is mostly about choosing the right product and preparing the joint. We remove what’s there first, the joint is cleaned and backed where needed, then the new sealant goes in. If you have threshold joints that have opened or worn and skirting caulk that keeps splitting, we can help, whatever the surface.

Older homes in small places like South Harting often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.

Every job is covered by a 12-month guarantee.

Questions from South Harting

Will you come out to South Harting?

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

Do you cover South Harting for floor joint sealing?

Yes, South Harting 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, and we’ll give you a clear price.

What causes gaps between the floor and skirting?

Movement from drying timber and settling floors opens the gap. Rigid fillers split, so we use a flexible sealant.

Do the sealants smell?

Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.

Is there a guarantee?

Yes. Each job is guaranteed for twelve months.

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.

Do you work on commercial floors?

Yes. We clean out the joints and reseal them with a product suited to the floor. Let us know about the traffic.

Can you add a movement joint to a tiled floor?

Often, yes, at the edges and along suitable lines. The grout is raked out and replaced with a flexible sealant in a colour to suit, giving the floor room to move.

Quotes for floor joint sealing in South Harting

We quote each job individually. This is what makes a difference:

  • Access and height
  • How much old sealant there is and how hard it is to remove
  • Which sealant suits the joint
  • The number of rooms or windows

The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and agree the price before starting.

Helping us quote

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • If someone has resealed it before
  • Roughly how big the job is
  • Where the property is
  • A few pictures by email, if you can

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.

When to call us in South Harting

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

Common reasons people contact us are:

  • Floor edges that trap water and grime
  • Caulk that has cracked where the floor moves
  • Perimeter joints in tiled floors filled with grout
  • Worn sealant at door thresholds

Schools such as Harting CofE Primary School are buildings too, and floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

How the visit works

On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work starts. Most jobs take a few hours for most rooms, longer for large commercial floors. In a small place like South Harting, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. The room is cleared along the joints so we can reach them.
  2. Old material is removed from the joint.
  3. We clean and dry the edges of the joint.
  4. We apply a flexible sealant suited to the floor.
  5. We check the joints and explain the aftercare.

Preparing for the visit

  • Let us know about earlier repairs to the joints
  • Tell us about access, such as stairs, a lift or high-level joints
  • Tell us about any water getting in

Why deal with it now?

Open joints along wet floors let water into the subfloor and behind skirting. Dealing with it early keeps the repair to the joint. In a small place like South Harting, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear price for the lot.

Why book with us

  • ARBOMaster approved applicator
  • We leave the area clean and tidy
  • White, clear, grey or another colour, product permitting
  • Trusted Arbo and Everbuild sealants

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.

Aftercare tips

Once the sealant has cured, a few habits help it last:

  • Vacuum floor joints regularly to stop grit building up
  • Use a well-wrung mop rather than flooding the floor
  • Look at floor joints each spring
  • Have a cracking tiled floor checked before tiles break

Do not paint over silicone. If you plan to paint, we’ll use a paintable product.

Once concrete joint edges start to break, wheels make it worse. Sealing them early protects the edges.

DIY versus a professional finish

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
