Book floor joint sealing in Walkern

How it works

You do not need to clear the whole room or building, only the area right around the joints. We protect the rest, and the job takes a few hours, depending on the length of joint for a typical job. Somewhere like Walkern needs a little journey planning: 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. We apply the sealant in a colour that suits the floor.
  5. The joint is tooled neatly and the cure time explained.

Preparing for the visit

  • Let us know if you’ve seen damp or leaks
  • Let us know about stairs, lifts or work at height
  • Let us know about parking restrictions

Floor joint sealing in Walkern

Floors move, and the joint where they meet a wall, skirting, threshold or another floor has to move with them. We seal skirting gaps, tiled floor movement joints and concrete floor joints. If you have open gaps along the bottom of skirting boards and caulk that has cracked where the floor moves, we can help, whatever the surface.

Around Walkern, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.

You are covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

Keeping the joints in good condition

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

  • Avoid caulk in bathrooms and kitchens
  • Keep floor cleaning water to a minimum at the edges
  • Keep dirt out of the joints
  • Keep heavy wheels off new concrete joints until cured

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.

Leave it or put it right?

The right product depends on the floor and the traffic: skirting and tiled floors need flexibility, wet areas need water resistance and concrete needs a product suited to wheels. Getting that choice wrong is a common reason joints fail. In a small place like Walkern, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

Floor joint sealing in Walkern: local notes

Floors around Hertfordshire run from suspended timber in older homes to concrete in newer houses and units, and they don’t all move the same way. The joint at the skirting or threshold has to allow for that.

For buildings such as Parish Church of St Mary the Virgin, floor and skirting joints in halls and kitchens wear like any others. Schools such as Walkern Primary School are buildings too, and floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. Letting a property close to Stevenage station? Then gaps at skirtings and thresholds are worth sealing between tenancies.

Can I do it myself?

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

How much does floor joint sealing cost in Walkern?

Size, access and the old material all affect the cost. Ask us for a quote.

What affects the cost of floor joint sealing

There’s no set price list, because no two jobs are the same. The quote depends on:

  • The number of rooms or windows
  • The number and length of the joints
  • The old material and how stubborn it is
  • The type of sealant required

There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

What we need to know

What to tell us when you ask for a quote:

  • The rough size of the job
  • If someone has resealed it before
  • Where the job is, and your postcode
  • Photos by email, if that’s easy

The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that’s easy.

When it isn’t the sealant

We will not take on work that won’t last, so here’s what sealant can’t put right:

  • Loose, hollow or cracked tiles, which need a tiler
  • Movement too big for a sealant joint
  • Floors that are uneven or need levelling

If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.

Joints and surfaces we work on

  • Wet room & bathroom floors
