St Margarets: your questions answered

Do you cover smaller places like St Margarets?

Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Is St Margarets in your area for floor joint sealing?

Yes, St Margarets is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.

Is there a guarantee?

Yes: twelve months. If anything is not right with the work within the year, let us know and we’ll sort it.

Do you remove the old sealant?

Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.

What information do you need?

Just the basics: where it is, what you’ve noticed and how we reach it. Then phone 0345 464 0079 or send us an email.

Is it worth trying it myself?

It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.

Can you quote for more than one area?

Yes. More than one area can go on one quote.

Can tenants book the work?

Yes. Ask your landlord first, and we can send them the quote if that helps.

Floor joint sealing in St Margarets, done properly

Gaps along the bottom of skirting are common in new and older homes alike. Caulk tends to crack there, so we close it with a flexible sealant instead. If you have skirting caulk that keeps splitting and floor edges that trap water and grime, we can put it right, whatever the surface.

Work in a small place like St Margarets just needs the journey and access planning, and the work itself is the same as on any site.

The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

How the job changes by surface

Tiled floors

When grout cracks along a straight line, the floor is telling you it needs to move. That line is converted to a flexible joint if it’s in the right place.

Thresholds

Two different floors meeting at a threshold move differently. We bridge them with a flexible bead.

What floor joint sealing looks like in St Margarets

Floors around Hertfordshire run from suspended timber in older homes to concrete in newer houses and units, and they don’t all move the same way. That is why the skirting and threshold joints need a flexible seal.

If you let a flat or house near St Margarets (Herts) station, gaps at skirtings and thresholds are worth sealing between tenancies. Schools such as The Cranbourne Primary School are buildings too, and floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. For buildings such as Parish Church of St Andrew, joints in its floors, skirtings and thresholds need resealing as they wear.

Aftercare tips

No joint lasts for ever, but care makes a real difference. Our tips:

  • Get cracks along tile grout lines looked at early
  • Lift furniture rather than dragging it across joints
  • Check the sealant is paintable before decorating
  • Keep floor cleaning water to a minimum at the edges

Mop with a well-wrung mop rather than flooding the floor. Keeping the edges drier helps the sealant last longer.

Concrete joints damaged by traffic get worse quickly. Early resealing helps keep the joint intact.

For landlords and businesses

We work for landlords and agents as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.

Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.

Should I try it myself first?

Some sealant jobs are within reach of a careful DIYer, such as a straightforward 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 fails, we can still redo it.

What we do, step by step

We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take a morning or an afternoon for most homes. For a village or hamlet like St Margarets, the journey is planned in advance: 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 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. The chosen sealant goes in, coloured to suit the floor.
  5. The joint is tooled neatly and the cure time explained.

Before we arrive

  • Let us know if you’ve seen damp or leaks
  • Mention any tricky access
  • Tell us if parking is tricky

Why it’s worth doing now in St Margarets

Left open, concrete joints break down under traffic. A sealed joint supports the edges and keeps the damage down. Older cottages and farmhouses around St Margarets can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we will go through it with you.
