Floor joint sealing in Leverstock Green

Floor joint sealing in Leverstock Green

Large tiled floors, and those over underfloor heating, often need movement joints. Where one is needed, we rake out the grout along the right line and replace it with flexible sealant. We work on concrete floor joints, commercial floors and thresholds, and common reasons people get in touch are gaps between floors and kitchen plinths and threshold joints that have opened or worn.

Homes around Leverstock Green range from older cottages to newer houses, and their floors range just as widely, each moving in its own way. Skirting and threshold joints need a sealant that suits the floor.

We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

What the job involves on each surface

Tiled floors

Perimeter joints in tiled floors should be sealant, not grout. We rake out any grout there and reseal.

Concrete floor joints

Concrete floors have sawn or formed joints to control cracking. We reseal them with a floor-joint product suited to the traffic.

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.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

What we do, step by step

Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a morning or an afternoon for most homes. For a job in Leverstock Green, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. We clear the edges of the floor so the joints are easy to reach.
  2. We take out the cracked caulk, grout or old sealant.
  3. We clean and dry the edges of the joint.
  4. A flexible sealant suited to the floor is applied and tooled.
  5. We check the joints and explain the aftercare.

How to prepare

  • Try not to wet indoor joints just before the visit
  • Let us know about parking restrictions
  • Clear the area around the work

Advice

Work for landlords, hotels and businesses

From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.

Why act early in Leverstock Green

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. Using the wrong one is why many floor joints fail. In an older home around Leverstock Green, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.

The cost reflects the work involved, not guesswork. That is why we ask about the job first and send you a clear quote before work begins.

Floor joint sealing around Leverstock Green

Leverstock Green is part of Hemel Hempstead, one of the post-war new towns. Hemel Hempstead has kept growing, with newer neighbourhoods added to the original town, so brand-new homes and homes from the post-war decades sit within a short drive of each other. Older homes need their sealant and floor joints renewing, newer ones checking at snagging. Across Hertfordshire, 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.

Letting a property close to Apsley station? Then open skirting and floor joints collect dirt and water, so seal them while the property is empty. Schools such as Leverstock Green Church of England Primary School are buildings too, and entrance and corridor floor joints take a lot of traffic. Community buildings like Church of Holy Trinity are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.

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 will send you a clear quote.

What do you need from me for a quote?

Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.

We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.

It depends on the job, so we quote each one individually. For a quick quote, ring 0345 464 0079 or email us and let us know what needs doing and where.

Can I add another job to the visit?

Yes, and it often makes sense. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.

How to look after the new joints

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

  • Keep caulk for dry, still joints only
  • Look at floor joints each spring
  • Do not slide heavy items over sealed joints
  • Vacuum floor joints regularly to stop grit building up

Have a look at the joints once the heating season is over. Small gaps at the ends can be touched up early on.

Sealing a gap while it’s small is a quick job. Ignored, they fill with dirt and open further over time.
