Need floor joint sealing in Gosport?

What happens on the day

You don’t need to clear the whole room or building, only the area right around the joints. We protect the rest, and the job takes a morning or an afternoon for most homes for a typical job. Somewhere as small as Gosport, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. First we check the joint and the floor and agree which sealant suits it.
  2. Whatever is in the joint now, whether caulk, grout or sealant, comes out.
  3. The joint is vacuumed clean, with backing fitted wherever depth matters.
  4. We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
  5. Finally we tool it smooth and explain when the floor can be used and cleaned.

Before we arrive

  • For business premises, tell us about site rules or sign-in
  • Plan for the work area to be out of bounds to pets and children
  • Clear the area around the work

Floor joint sealing in Gosport

Thresholds are where two floors, or a floor and a door, meet. We use a flexible product that suits both floors so the joint stays neat. We work on commercial floors, thresholds and tiled floors, and the jobs we see most are chipped and open joints in warehouse floors and cracked caulk along skirting in bathrooms and kitchens.

For a small place like Gosport, the journey and access are planned in advance, and once on site, the job is the same as anywhere.

Your job is guaranteed for a year, as with all our work.

Floor joint sealing in Gosport: 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. The joint at the skirting or threshold has to allow for that.

Schools such as Ampfield Church of England Primary School are buildings too, and floor and threshold joints in busy corridors wear quickly and are best resealed early. Community buildings like Church of St Mark are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear. Letting a property close to Chandlers Ford station? Then gaps at skirtings and thresholds are worth sealing between tenancies.

Leave it or put it right?

Waiting until the next redecoration can mean a winter of draughts and dirt in the gaps. Sealing them now is a short job for most homes. Older cottages and farmhouses around Gosport can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

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

DIY sealant or a professional job?

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

Landlord and commercial work in Gosport

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

Housing providers, facilities teams and property managers book us too. We can quote a run of properties together.

Quotes for floor joint sealing in Gosport

We do not publish a price list, because jobs vary so much. The quote depends on:

  • Any working-time requirements on site
  • The product the joint needs
  • How many rooms, windows or areas are involved
  • Whether there’s mould to deal with

Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

What we need to know

When you call or email, these details help:

  • Where the job is, and your postcode
  • Access, such as stairs, a lift or height
  • If it’s domestic, commercial or a hotel
  • The problem you’ve noticed

For a quick quote, get us on the phone, or email us if that’s easier. Tell us about the joints that need doing and we’ll explain what’s involved before giving you a price.

What sealant work cannot fix

In fairness, there are a few things sealant will not fix:

  • Failed waterproofing under a wet room floor
  • Structural movement or subsidence
  • Tiles that have lifted or broken

If in doubt, call 0345 464 0079 or send us an email and we will say what we think.

Different surfaces, different methods

Tiled floors

The edge of a tiled floor, where it meets the wall or skirting, should be a flexible joint. Grout at the edge is removed and replaced with sealant.

Thresholds

Thresholds take daily traffic, so we choose a hard-wearing, flexible product and tool it flush.
