Floor joint sealing near Langstone

How the job changes by surface

Commercial floors

Floor joint work in businesses can be planned around your hours. We can arrange out-of-hours work where it’s needed.

Wet room and bathroom floors

Bathroom floors meet baths, trays, panels and skirting. We seal them with anti-fungal sanitary silicone.

Floor joint sealing in Langstone, done properly

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. We work on commercial floors, tiled floors and thresholds, and the jobs we see most are tiled floors with no room to move and open gaps along the bottom of skirting boards.

Somewhere as small as Langstone, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.

All of our work is guaranteed for twelve months, in Langstone and everywhere else we cover.

Langstone: your questions answered

Do you cover smaller places like Langstone?

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

Can you help a landlord with a rental near Havant station?

Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or email us with the details for a clear quote.

Which products do you use?

We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll explain our choice.

Why not just use caulk?

Not where the floor moves or gets wet. It splits once the floor shifts and the gap reopens. A flexible sealant is the better choice.

Do the sealants smell?

Some sealants have a smell while they cure. Ventilation helps.

Do you seal floor joints in bathrooms and kitchens?

Yes. These joints get wet every time the floor is cleaned, so a flexible silicone is the right choice.

Will I be able to paint over the new joint?

Where you plan to paint, we do. Silicone in bathrooms and kitchens cannot be painted, so tell us your plans.

Can you match the sealant colour?

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

Joints and finishes in Langstone homes

Across Hampshire, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.

If you look after a building such as Bosmere Junior School, entrance and corridor floor joints take a lot of traffic. For landlords with property near Havant station, gaps at skirtings and thresholds are worth sealing between tenancies.

Should I try it myself first?

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

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

What sealant work can’t fix

We will always be straight with you, so here’s what sealant cannot fix:

  • Movement too big for a sealant joint
  • Tiles that have lifted or broken
  • Water getting under the tiles from elsewhere

If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before you book.

Where we work in Langstone

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

What happens if it’s left?

Filling a skirting gap with caulk looks fine at first, but the movement soon cracks it. A flexible sealant moves with the floor and keeps the joint sealed. Where a wall is exposed, as many are in small places like Langstone, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

  • Full insurance on every job
  • Approved under the ARBOMaster scheme

How to look after the new joints

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Act on grout cracks that run in a straight line
  • Keep floor cleaning water to a minimum at the edges
  • Sweep along the edges of the floor
  • Cone off fresh joints until they’re ready

Follow the cure time before walking on or cleaning the joint. Light foot traffic is usually fine sooner than wet cleaning or wheels, and we’ll tell you both.

A gap under the skirting collects dust and lets draughts through. Sealing it early keeps the room cleaner.

Do you need floor joint sealing in Langstone?

Decorators’ caulk is often used along skirting because it’s cheap and paintable. It cracks where there’s movement or water, which is why so many skirting joints look broken.

The problems people normally mention when they call are:

  • Grout cracking in a straight line across a floor
  • Gaps opening between the floor and skirting
  • Concrete floor joints that have broken down
  • Dirt and water collecting in open floor joints

If you look after a church, hall or community building such as Saint Nicholas' Chapel, floor and skirting joints in halls and kitchens wear like any others.

What your quote should include

  • What the cure time is
  • Whether they seal over old material or remove it
  • What happens if they find a problem under the old sealant
  • The length of the guarantee

Our hiring checklist

How it works

Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for most rooms, longer for large commercial floors. For a village or hamlet like Langstone, the journey is planned in advance: let us know about lanes, gates and parking. 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. Any old caulk, grout or sealant is raked or cut out.
  3. We vacuum out the joint and add backing where the depth needs setting.
  4. The chosen sealant goes in, coloured to suit the floor.
  5. We tool it neatly and tell you when it can be walked on and cleaned.

Preparing for the visit

  • Mention any leaks or damp you’ve noticed
  • On commercial sites, let us know about site rules
  • Let us know about parking restrictions
