Trusted floor joint sealing in Letty Green

Landlords, agents and businesses in Letty Green

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

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.

Floor joint sealing for homes and businesses in Letty Green

Gaps along the bottom of skirting are common in new and older homes alike. Decorators’ caulk normally cracks where there’s movement, so we close it with a flexible sealant instead. We work on thresholds, skirting boards and commercial floors, and common reasons people get in touch are open gaps along the bottom of skirting boards and open joints that fill with dirt.

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

A one-year guarantee comes with the work, just as it does everywhere we cover.

Common questions in Letty Green

Can you help a landlord with a rental near Hertford North station?

Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.

Do you cover smaller places like Letty Green?

Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Can you do several jobs on one visit?

Yes. Just list everything you need and we will quote it together.

Will there be a smell?

That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.

When can I walk on the floor?

We give you a cure time for each joint. Light use comes first, cleaning and heavy traffic later in most cases.

Are you an approved applicator?

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

Is there a guarantee?

Yes. There’s a 12-month guarantee on every job.

Can you seal over the old sealant?

No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.

How the job changes by surface

Skirting boards

Skirting-to-floor joints are a regular job for us. The old caulk is removed first so the bead sits on a clean surface.

Tiled floors

A crack running along a grout line is often a sign of a missing movement joint. That line is converted to a flexible joint.

DIY versus a professional finish

A DIY attempt does not rule out a professional job. We cut it out and start again.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

How the visit works

Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for most rooms, longer for large commercial floors. Somewhere as small as Letty Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  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.

Getting ready for the visit

  • Let us know about parking restrictions
  • For indoor joints, keep the area dry beforehand if you can
  • Clear the area around the work

Advice

Signs you need floor joint sealing in Letty Green

Some floors were never given a perimeter gap or movement joint. As it expands, the edges lift or crack, and the sealant or grout breaks.

Common reasons people contact us include:

  • Rigid edge joints in tiled floors
  • Chipped and open joints in warehouse floors
  • Caulk that has cracked where the floor moves
  • Open gaps along the bottom of skirting boards

If you look after a building such as Hertingfordbury Cowper Primary School, entrance and corridor floor joints take a lot of traffic.

What your quote should include

  • What the quote includes, VAT included or not
  • Whether they’re fully insured
  • What the cure time is
  • Is the old sealant removed completely?

How to choose a mastic man

Honest limits

A few problems are outside what sealant work can do:

  • Concrete repairs beyond the joint
  • Floors that are uneven or need levelling
  • Loose, hollow or cracked tiles, which need a tiler

Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before you book.

What we seal

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

What affects the cost of floor joint sealing

Every job gets its own quote. These are the things that affect it:

  • How easy the joints are to reach
  • Whether there’s mould to deal with
  • The product the joint needs
  • Whether old sealant or filler has to be cut out

Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

Asking for a quote

To make quoting easier, please include:

  • Whether it’s a home or a business
  • If someone has resealed it before
  • The problem you’ve noticed
  • Roughly how big the job is

There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To get started, phone 0345 464 0079 or drop us an email.
