How we quote for floor joint sealing

Jobs vary more than people expect. What affects the quote:

  • Which sealant suits the joint
  • When we can work, for business premises
  • How many rooms, windows or areas are involved
  • Whether old sealant or filler has to be cut out

A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

What we need to know

To make quoting easier, let us know:

  • If someone has resealed it before
  • Where the property is
  • Whether it’s a home or a business
  • A few photos by email, if you can

We do not publish a price list, as no two jobs are quite the same. Instead, we give you a clear price for your job. To get started, ring 0345 464 0079 or send us an email.

Floor joint sealing for homes and businesses in Middle Wallop

Large tiled floors, and those over underfloor heating, often need movement joints. We can turn a line of grout into a movement joint by replacing it with flexible sealant in a matching colour. If you are dealing with open joints around bathroom floor edges and tiled floors with no room to move, we can help.

Older homes in small places like Middle Wallop 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.

The process

We work through the job in order: protect, prepare, seal, tidy. Typically it takes a morning or an afternoon for most homes and we leave things clean and tidy. For a village or hamlet like Middle Wallop, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. The room is cleared along the joints so we can reach them.
  2. Old material is removed from the joint.
  3. Edges are cleaned and dried.
  4. A flexible sealant suited to the floor is applied and tooled.
  5. We check the joints and explain the aftercare.

Getting ready for the visit

  • Try not to wet indoor joints just before the visit
  • Let us know about earlier repairs to the joints
  • Mention any leaks or damp you’ve noticed

How to get a quote

Advice

What sealant work cannot fix

We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:

  • Failed waterproofing under a wet room floor
  • Subfloor problems that need a flooring contractor
  • Loose, hollow or cracked tiles, which need a tiler

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

Where we work in Middle Wallop

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

When to call us in Middle Wallop

Floors and walls move a little with the seasons. Heating dries timber and opens gaps along the skirting, then close again in damper months.

Any of these means the joints need attention:

  • Perimeter joints in tiled floors filled with grout
  • Gaps between floors and kitchen plinths
  • Caulk that has cracked where the floor moves
  • Gaps at thresholds between rooms

Letting a property close to Grateley station? Then open skirting and floor joints collect dirt and water, so seal them while the property is empty.

Our hiring checklist

Different surfaces, different methods

Thresholds

A threshold is where floors and frames meet. We seal them with a flexible sealant that suits both sides.

Wet room and bathroom floors

Bathroom floors meet baths, trays, panels and skirting. They’re sealed with a flexible, anti-fungal silicone to keep water out of the edges.

DIY versus a professional finish

A careful DIYer can reseal a simple joint, 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.

Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

Aftercare tips

Simple care keeps the joints in good condition. Our advice:

  • Have a cracking tiled floor checked before tiles break
  • Cone off fresh joints until they’re ready
  • Avoid sloshing water against skirting
  • Don’t paint over silicone

Avoid flooding the floor when you clean. Less water at the edges helps the joints last.

A tiled floor that cracks along a line will keep cracking until it can move. Adding a movement joint early can stop cracks spreading to the tiles.

Floor joint sealing in Middle Wallop: local notes

Floors around Hampshire run from suspended timber in older homes to concrete in newer houses and units, and they do not all move the same way. That’s why the skirting and threshold joints need a flexible seal.

Schools such as Wallop Primary School are buildings too, and floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. Community buildings like Church of St Andrew are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.

Middle Wallop: your questions answered

Do you work for landlords with property near Grateley station?

Yes, we work for landlords and letting agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.

Is Middle Wallop within the area you cover?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

My floor grout keeps cracking in a line. Can you help?

Often, yes. Straight cracks in grout often show where a movement joint was needed. We replace that grout with a flexible joint.

Why has a gap opened under my skirting?

Timber floors and skirting shrink and swell through the year. We close it with a flexible sealant that moves with the floor.

Can you match the sealant colour?

Most of the time, yes. We’ll explain which colours are available.

Do you hold any approvals?

Yes. We hold ARBOMaster approved applicator status and we are fully insured too.

Do I have to be there?

Access is agreed with you when the job is booked. Indoors, that generally means someone at home.

How long before the joint can take traffic?

It depends on the product and the conditions. Before we leave, we tell you when it can be walked on, mopped and driven over so you can plan.
