About our floor joint sealing in Crouch End

Concrete floors in warehouses and units have joints that take heavy wear. We reseal them with a product chosen for the movement and the traffic. If you have gaps between floors and kitchen plinths and gaps at thresholds between rooms, we can help, on wet room & bathroom floors, commercial floors and skirting boards alike.

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 Crouch End and beyond.

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

Common questions in Crouch End

Can you do floor joint sealing in Crouch End?

Yes. Our work covers London and the South East, and Crouch End is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.

Is parking an issue for floor joint sealing in Crouch End?

In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.

Where are you based?

Mr Mastic is based in Crawley. Our applicators cover Crouch End, along with the rest of our area.

What sealant do you use?

Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we are using and why.

Can tenants book the work?

We’re happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.

Will there be a smell?

Possibly a little. Any smell clears as the sealant cures.

What do you need from me for a quote?

A short description and the location. We’ll ask anything else we need to know.

Do you take out the old sealant first?

Yes. All of the old material is cut out and the joint cleaned before resealing.

How the job changes by surface

Commercial floors

Commercial washrooms and kitchens have floor joints that get wet constantly. They’re resealed with a flexible, water-resistant sealant.

Skirting boards

Skirting pulls away from the floor as floors shrink and settle. A flexible sealant closes the gap without cracking in a colour to suit.

The process

Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a morning or an afternoon for most homes. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.

  1. We start by checking the floor, the joint and what traffic it takes.
  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. The joint is tooled neatly and the cure time explained.

Preparing for the visit

  • Mention any parking rules near the property
  • Mention any sign-in or site rules at work premises
  • Tell us about any previous sealing or DIY attempts

Advice

Quotes for floor joint sealing in Crouch End

Call for a quick quote. What matters most is:

  • Working hours on commercial sites
  • Any mould that needs treating
  • Whether the work is at height
  • The product the joint needs

No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

What we need to know

Photos help, but a description is a good start. Please mention:

  • Where the job is, and your postcode
  • Any access issues, like height or stairs
  • If it’s domestic, commercial or a hotel
  • What’s wrong with the joints now

Need a quote? Please ring 0345 464 0079 or email us and tell us about the job. We will explain what we’d do and send you a clear quote before any work starts.

When it isn’t the sealant

We’d rather tell you now than do work that will not last, so these are the limits:

  • Failed waterproofing under a wet room floor
  • Floors that are uneven or need levelling
  • Tiles that have lifted or broken

If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before booking.

Surfaces we seal

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

Landlord and commercial work in Crouch End

In hotels, rooms out of use cost money, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

Why act early in Crouch End

Open joints along wet floors let water into the subfloor and behind skirting. Sealing them now keeps the problem at the surface. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Crouch End, the repair is bigger than a sealant job.

What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

Why book with us

  • Trusted Arbo and Everbuild sealants
  • Over 20 years’ experience
  • We never seal over old sealant
  • 180+ five-star Google reviews

How to look after the new joints

Looking after new joints is easy:

  • Use furniture pads near skirting
  • Keep caulk for dry, still joints only
  • Cone off fresh joints until they’re ready
  • Act on grout cracks that run in a straight line

Silicone sealant is not made to take paint. If you plan to paint, we will use a paintable product.

Concrete joints damaged by traffic get worse quickly. Sealing them early protects the edges and the floor safer.

Floor joint sealing in Crouch End: local notes

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 they do not all move the same way. The joint at the skirting or threshold has to allow for that.

As a London address, Crouch End can be tricky for parking: let us know about parking bays, permits or a driveway. If you let a flat or house near Crouch Hill station, gaps at skirtings and thresholds are worth sealing between tenancies. Schools such as Rokesly Infant & Nursery School are buildings too, and entrance and corridor floor joints take a lot of traffic.
