Roe Green questions

I let a flat near Ashwell & Morden station. Can you help?

Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.

Is Roe Green in your area for floor joint sealing?

Yes, Roe Green is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear quote.

Are you fully insured?

Yes. We’re fully insured.

Can sealant along the skirting be painted?

If you tell us beforehand, yes. Joints that will be painted get a paintable product and wet areas get silicone.

Is there a guarantee?

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

Can new sealant go over the old?

No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.

Do I need to be at home?

That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.

Do the sealants smell?

There can be a smell while the sealant cures, but it fades. Opening a window helps.

Floor joint sealing in Roe Green

Where skirting is painted, we can use a flexible sealant that takes paint. For bathrooms and kitchens, silicone is generally the better choice because it handles water. We work on tiled floors, skirting boards and concrete floor joints, and people most often call us about grout used at the floor edge instead of sealant and concrete floor joints that have broken down.

Older homes in small places like Roe Green often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.

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.

Different surfaces, different methods

Concrete floor joints

We clean concrete joints out thoroughly before sealing first. Backing goes in where the depth needs controlling.

Commercial floors

Washroom and kitchen floors in commercial buildings need sound edge joints. We reseal them with a sealant suited to wet areas.

Landlord and commercial work in Roe Green

From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly 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.

What we do, step by step

Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for most rooms, longer for large commercial floors. Somewhere like Roe Green needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We start by looking at the floor, the gap and the traffic, then choose the product.
  2. Whatever is in the joint now, whether caulk, grout or sealant, comes out.
  3. We clean and vacuum the joint and fit backing where the depth needs setting.
  4. We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
  5. Finally we tool it smooth and explain when the floor can be used and cleaned.

How to prepare

  • Mention any leaks or damp you’ve noticed
  • Mention any sign-in or site rules at work premises
  • Mention if the joints have been sealed before

To be straight with you, some problems need a different trade:

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

Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.

Joints and surfaces we work on

Floor joint sealing in Roe Green: local notes

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.

For buildings such as Church of All Saints, joints in its floors, skirtings and thresholds need resealing as they wear. Schools such as Sandon Junior Mixed and Infant School are buildings too, and floor and threshold joints in busy corridors wear quickly and are best resealed early. Rented homes near Ashwell & Morden station change hands often, and open skirting and floor joints collect dirt and water, so seal them while the property is empty.

DIY sealant or a professional job?

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

Helping us quote

When you call or email, it’s useful to know:

  • What the problem is, such as mould, gaps, leaks or cracking

How to look after the new joints

Looking after new joints is easy:

  • Avoid caulk in bathrooms and kitchens
  • Ask before painting over a sealed joint
  • Act on grout cracks that run in a straight line
  • Sweep along the edges of the floor

Keep heavy traffic off resealed concrete joints for the cure time we give you. Cone off the area if needed while it cures.

Small gaps are quick to seal. Left alone, they collect dirt and widen and are harder to clean out.
