When to call us in Petersfield

Concrete floor joints break down when traffic runs over open or failed joints. Pallet trucks and trolleys knock the edges away.

Most people get in touch when they notice one of these:

  • Dirt and water collecting in open floor joints
  • Failed joint filler in concrete floors
  • Tiled floors with no room to move
  • Threshold joints that have opened or worn

Community buildings like St Peter's Church are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.

What to look for in a quote

  • How the surfaces are prepared before sealing
  • How much experience the applicator has
  • What happens if the job turns out different
  • Whether the sealant suits the joint

Floor joint sealing for homes and businesses in Petersfield

Every floor moves a little, so its edges need a joint that can flex. Skirting-to-floor gaps, tiled floor joints and concrete joints are all sealed. Common call-outs are for cracked caulk along skirting in bathrooms and kitchens and dirt and water collecting in open floor joints, on wet room & bathroom floors, commercial floors and skirting boards.

In a town like Petersfield, older houses sit alongside newer estates, with new homes still going up on the edge of many towns. Whether a house is brand new or a few years old, sealant and floor joints are often the first snags to show.

All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

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

Rented homes near Petersfield station change hands often, and open skirting and floor joints collect dirt and water, so seal them while the property is empty. Managing a site like Petersfield Infant School? Then entrance and corridor floor joints take a lot of traffic.

DIY versus a professional finish

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

What happens on the day

Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a morning or an afternoon for most homes. A visit in Petersfield needs access to the work and a place to park close by. For outside work, let us know about side access, gates and any upper-floor joints.

  1. We start by looking at the floor, the gap and the traffic, then choose the product.
  2. Whatever is in the joint now, whether caulk, grout or sealant, comes out.
  3. We clean and vacuum the joint and fit backing where the depth needs setting.
  4. The sealant goes in, chosen for the floor and coloured to suit it.
  5. Finally we tool it smooth and explain when the floor can be used and cleaned.

Before we arrive

  • Keep children and pets away from the work area
  • Let us know if you’ve seen damp or leaks
  • Let us know about parking restrictions

Advice

How we quote for floor joint sealing

You will get a clear quote before any work starts. It takes into account:

Different surfaces, different methods

Concrete floor joints

Hard wheels break down the edges of open joints. Sealing them supports the edges and stops debris collecting.

Skirting boards

Skirting gaps are one of the most common floor joints we seal. The old caulk is removed first so the new sealant bonds.

Aftercare tips

To keep the joints looking good and working properly:

  • Do not paint over silicone
  • Keep dirt out of the joints
  • Keep caulk for dry, still joints only
  • Get cracks along tile grout lines looked at early

Mop with a well-wrung mop rather than flooding the floor. Keeping the edges drier helps the sealant last longer.

In wet areas, an open floor joint lets water reach the subfloor. Resealing early keeps it out.

Your questions about floor joint sealing in Petersfield

Do you cover Petersfield for floor joint sealing?

Yes, Petersfield is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear quote.

Do you work for landlords with property near Petersfield station?

Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. Just ring 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.

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.

Is it messy?

We keep the work tidy. Nearby surfaces are protected.

Will I be able to paint over the new joint?

It depends on the sealant, so let us know first. Joints that will be painted get a paintable product and wet areas get silicone.

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. The old sealant has to come out completely.

Do the sealants smell?

There can be a smell while the sealant cures, but it fades. Ventilation helps.

Do you remove the old sealant?

Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
