Common reasons people contact us are:

  • Caulk that has cracked where the floor moves
  • Grout cracking in a straight line across a floor
  • Gaps opening between the floor and skirting
  • Floor edges that trap water and grime

If you let a flat or house near Bowes Park station, a tidy floor and skirting joint helps a rental look ready for the next tenant.

How to choose a mastic man

Floor joint sealing for homes and businesses in Bounds Green

Floor joint sealing is mostly about choosing the right product and preparing the joint. We remove what’s there first, the joint is cleaned and backed where needed, then the new sealant goes in. We work on wet room & bathroom floors, concrete floor joints and thresholds, and the jobs we see most are grout cracking in a straight line across a floor and perimeter joints in tiled floors filled with grout.

Across London, commercial floors have movement joints that break down under heavy foot traffic, while new homes need a neat, sound finish around frames, baths and kitchens before handover, in Bounds Green and beyond.

Whatever the size of the job, it’s backed by our 12-month guarantee in Bounds Green and across Greater London.

Helping us quote

To help us quote quickly, let us know:

  • How many joints, rooms or windows are involved
  • Where the job is, and your postcode
  • Photos by email, if that’s easy

Surface by surface

Thresholds

Thresholds between rooms meet two floors and often a door frame. We seal them with a flexible sealant that suits both sides.

Commercial floors

Commercial floors take more traffic than most homes. We talk through the traffic and choose a sealant suited to it.

Honest limits

It helps to know what we can’t do too:

  • Water getting under the tiles from elsewhere
  • Loose, hollow or cracked tiles, which need a tiler
  • Movement too big for a sealant joint

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

How it works

We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours, depending on the length of joint. In Bounds Green, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.

  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. A flexible sealant suited to the floor is applied and smooth it.
  5. Finally, we check the work and talk you through aftercare.

Getting ready for the visit

  • Mention any sign-in or site rules at work premises
  • Tell us about access, such as stairs, a lift or high-level joints
  • Mention any parking rules near the property

Landlord and commercial work in Bounds Green

Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.

Aftercare tips

Aftercare is simple:

  • Vacuum floor joints regularly to stop grit building up
  • Check skirting joints after the heating season
  • Act on grout cracks that run in a straight line
  • Do not paint over silicone

Follow the cure time before walking on or cleaning the joint. Feet are generally fine before mopping or wheeled traffic.

Open skirting gaps let in draughts, dust and sometimes insects. Sealing it keeps the room tidier.

Floor joint sealing in Bounds Green: local notes

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. Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent.

As a London address, Bounds Green can be tricky for parking: let us know about parking bays, permits or a driveway. Schools such as Bounds Green Infant School are buildings too, and floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.
