Floor joint sealing for Haverstock homes and businesses

The process

There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the work takes a few hours, depending on the length of joint for a typical job. In a London area like Haverstock, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.

  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. 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.

Preparing for the visit

  • Let us know about stairs, lifts or work at height
  • For indoor joints, keep the area dry beforehand if you can
  • Move anything stored near the joints

Floor joint sealing for homes and businesses in Haverstock

Floor joint sealing is mostly about choosing the right product and preparing the joint. Old caulk, grout or failed sealant comes out first, then clean, back and seal the joint. Common call-outs are for threshold joints that have opened or worn and open gaps along the bottom of skirting boards, across tiled floors, wet room & bathroom floors and concrete floor joints.

From brand-new flats to converted terraces with new flooring, London has every kind of floor. Every joint between floor, skirting and threshold has to cope with some movement, in Haverstock as anywhere.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Joints and finishes in Haverstock homes

Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. Across Greater London, 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.

If you let a flat or house near South Hampstead station, gaps at skirtings and thresholds are worth sealing between tenancies. Managing a site like Fine Arts College? Then floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. As a London address, Haverstock can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Haverstock questions

Can you do floor joint sealing in Haverstock?

Yes. We work across London and the South East, and Haverstock is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.

I let a flat near South Hampstead station. Can you help?

Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.

Where are you based?

Our base is in Crawley, and we cover South East England, London and all of Scotland.

Can you reseal concrete floor joints in an industrial unit?

Yes, including warehouses, units, shops and offices. Work can be planned around your hours, and out-of-hours work can be arranged.

Is there a guarantee?

Yes: twelve months. If anything is not right with the work within the year, let us know and we will sort it.

How long will you be here?

That depends on how much there is to do, but as a guide it takes a few hours, depending on the length of joint. We’ll give you a better idea when we quote.

Can you add a movement joint to a tiled floor?

Often, yes. A crack along a grout line often means the floor needs room to move. We rake out that line and seal it with flexible sealant.

Do you hold any approvals?

Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.

Looking after it afterwards

So the new joints stay in good condition:

  • Act on grout cracks that run in a straight line
  • Walk round the room once a year and look at the edges
  • Lift furniture rather than dragging it across joints
  • Use a well-wrung mop rather than flooding the floor

Keep heavy furniture from dragging across the joints. Sharp edges can cut the sealant.

A tiled floor that cracks along a line will keep cracking until it can move. A flexible joint added early helps protect the tiles themselves.

Honest limits

Some problems need a builder, plumber or other trade rather than us:

  • Concrete repairs beyond the joint
  • Subfloor problems that need a flooring contractor
  • A tiled floor that needs relaying

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

Joints and surfaces we work on

Surface by surface

Skirting boards

Skirting gaps are one of the most common floor joints we seal. We take out any cracked caulk before sealing.

Commercial floors

Floor joint work in businesses can be planned around your hours. We can arrange out-of-hours work.

DIY versus a professional finish

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
