Questions from Andover

Is there a guarantee on floor joint sealing in Andover?

Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.

Do you work for landlords with property near Andover station?

Yes. We work for landlords and letting agents as well as householders. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.

Can grout be replaced with sealant on a tiled floor?

Often, yes. We replace the grout along a suitable line with flexible sealant in a matching colour. If tiles are loose, that needs fixing first.

Can new sealant go over the old?

No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.

Can you use decorators’ caulk instead?

Caulk can’t cope with movement or water. Skirting joints move with the floor, so a flexible sealant suits them better.

Is it messy?

No. We work neatly, protect the area around the joints and tidy up afterwards.

Do the sealants smell?

Possibly a little. It fades as the sealant cures.

How long does the job take?

Most jobs take a few hours, depending on the length of joint, including preparation and clearing up. We’ll confirm how long when we quote.

About our floor joint sealing in Andover

In kitchens and bathrooms, the joint where the floor meets a bath panel, plinth or skirting takes mop water every day. We seal them with a flexible, water-resistant sealant and stops dirt collecting. We work on commercial floors, thresholds and concrete floor joints, and common reasons people get in touch are chipped and open joints in warehouse floors and skirting caulk that keeps splitting.

Small business units and shops in a town like Andover have floors that take heavy wear. Threshold and floor joints are best resealed before their edges start breaking away.

The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or drop us an email.

How it works

Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours, depending on the length of joint. In Andover, parking is rarely complicated, though it helps to know about driveways or restrictions, and let us know if the work is upstairs, in a flat or up high outside.

  1. First, the floor type, the gap and the traffic are checked.
  2. We remove what’s in the joint now.
  3. The joint is vacuumed clean and backing fitted where needed.
  4. We apply the sealant in a colour that suits the floor.
  5. We tool it neatly and tell you when it can be walked on and cleaned.

Before we arrive

  • On commercial sites, let us know about site rules
  • Where the joints are inside, avoid wetting them before we arrive
  • Plan for the work area to be out of bounds to pets and children

Advice

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.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Floor joint sealing in Andover: local notes

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. That is why the skirting and threshold joints need a flexible seal.

For buildings such as Church of St Mary, joints in its floors, skirtings and thresholds need resealing as they wear. Managing a site like St John the Baptist Catholic Primary School? Then floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

Looking after it afterwards

To keep the joints looking good and working properly:

  • Keep floor cleaning water to a minimum at the edges
  • Mark off resealed joints in warehouses
  • Act on grout cracks that run in a straight line
  • Do not fill floor joints with caulk where they move or get wet

Silicone sealant isn’t made to take paint. If you plan to paint, we will use a paintable product.

Water getting into floor joints in bathrooms and kitchens can damage what’s underneath. A sound seal stops that happening.

Why act early in Andover

Regrouting a cracked line in a tiled floor rarely fixes it. If the floor needs to move there, the grout will crack again. A flexible movement joint is the fix. Around Andover, failed sealant lets water into hidden places, such as under the floor, behind a panel or into a wall. Whatever the joint, failed sealant only gets worse.

Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Wheels crossing an unfilled concrete joint chip its edges. Hard wheels damage the joint edges.

  • Threshold joints that have opened or worn
  • Cracked caulk along skirting in bathrooms and kitchens
  • Perimeter joints in tiled floors filled with grout
  • Tiled floors with no room to move

If you let a flat or house near Andover station, open skirting and floor joints collect dirt and water, so seal them while the property is empty.

  • What happens if the job turns out different
  • What preparation is included
  • How long to leave it before use

Choosing a sealant specialist

How the job changes by surface

Concrete floor joints

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

Skirting boards

On painted skirting, we can use a flexible sealant that takes paint. In wet rooms and kitchens, silicone is generally better.
