Floor joint sealing in Holloway

Floor joint sealing in Holloway

Tiled floors can crack along the grout when there’s no room for movement. Where one is needed, we rake out the grout along the right line and replace it with flexible sealant coloured to suit the grout. Typical jobs include skirting caulk that keeps splitting and chipped and open joints in warehouse floors, across tiled floors, thresholds and concrete floor joints.

London homes range from new-build flats to period conversions with new floors laid over old boards. Every joint between floor, skirting and threshold has to cope with some movement.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Signs you need floor joint sealing in Holloway

Floors and walls move a little with the seasons. In winter, with the heating on, timber dries and gaps open.

Any of these means the joints need attention:

  • Open gaps along the bottom of skirting boards
  • Open joints around bathroom floor edges
  • Concrete floor joints that have broken down
  • Caulk that has cracked where the floor moves

Schools such as Grafton Primary School are buildings too, and floor and threshold joints in busy corridors wear quickly and are best resealed early.

Before booking anyone

  • Whether they seal over old material or remove it
  • What product goes in the joint
  • What insurance they hold
  • What the cure time is

10 questions to ask before you book

Joints and finishes in Holloway homes

Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent. Across Greater London, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. That’s why the skirting and threshold joints need a flexible seal.

If you let a flat or house near Drayton Park station, gaps at skirtings and thresholds are worth sealing between tenancies. If you look after a church, hall or community building such as St Joseph and St Padarn's Church, floor and skirting joints in halls and kitchens wear like any others.

Holloway is about 2 miles north-west of Hoxton, in Greater London. Every kind of property in Holloway is covered for floor joint sealing. Every job comes with our 12-month guarantee. Holloway is one of 764 towns and villages in Greater London where we work.

Holloway: your questions answered

Is parking a problem for a job in Holloway?

London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.

I let a flat near Drayton Park station. Can you help?

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

Do I need to be at home?

It depends on the job. Inside work needs someone to give us access.

Can you add a movement joint to a tiled floor?

Often, yes, at the edges and along suitable lines. We remove the grout and seal the line with flexible sealant so the floor can move.

Do you seal kitchen plinths to the floor?

Yes. Floor edges in bathrooms and kitchens get wet at every clean, so we seal them with silicone suited to wet areas.

Are you an approved applicator?

Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.

Will you leave a mess?

No. We protect the surfaces around the joints, and we tidy up before we go.

Do you guarantee your work?

Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.

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.

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 doesn’t work out, we can still put it right.

What we cannot put right

Honest advice matters more to us than a booking, so here’s what new sealant will not do:

  • Cracked or broken concrete slabs
  • Failed waterproofing under a wet room floor
  • Bouncy or failing floorboards

If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before booking.

Where we work in Holloway

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

Work for landlords, hotels and businesses

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can be quoted together.

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 that we can handle for you.

Surface by surface

Thresholds

Two different floors meeting at a threshold move differently. A flexible sealant bridges them.

Skirting boards

Skirting-to-floor joints are a regular job for us. We take out any cracked caulk before sealing so the new sealant bonds.

Why act early in Holloway

Leaving skirting gaps until the next decorating job lets dirt and draughts in. Sealing them now is a short job. In a flat in Holloway, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.

Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.

Why book with us

  • Sealant colour chosen to suit
  • Trusted Arbo and Everbuild sealants
  • We never seal over old sealant
  • Neat joints and a tidy finish

See how sealant jobs are priced and our reviews.

How it works

We keep the work tidy and contained to the joints we’re treating. The job normally takes a few hours for most rooms, longer for large commercial floors, and we tell you how long to leave it before we go. In Holloway, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.

  1. The room is cleared along the joints so we can reach them.
  2. We take out the cracked caulk, grout or old sealant.
  3. We clean and dry the edges of the joint.
  4. We apply a flexible sealant suited to the floor and tooled.
  5. Finally, we check the work and talk you through aftercare.

Getting ready for the visit

  • Tell us about any water getting in
  • Plan for the work area to be out of bounds to pets and children
  • Let us know about parking restrictions
