Trusted floor joint sealing in Upstreet

Can I do it myself?

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, then guaranteed for a year.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Floor joint sealing in Upstreet

Floor joint sealing is mostly about choosing the right product and preparing the joint. Old caulk, grout or failed sealant comes out first, then clean, back and seal the joint. We are often asked to deal with cracked caulk along skirting in bathrooms and kitchens and open joints that fill with dirt, across concrete floor joints, skirting boards and wet room & bathroom floors.

For a small place like Upstreet, the journey and access are planned in advance, and the work itself is the same as on any site.

There’s a 12-month guarantee on every job, large or small.

What happens if it’s left?

Left open, concrete joints break down under traffic. A sealed joint supports the edges. Where a wall is exposed, as many are in small places like Upstreet, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.

How the job changes by surface

Skirting boards

If the skirting is painted, a paintable flexible sealant works well. Where water is involved, silicone is the better choice.

Concrete floor joints

Hard wheels break down the edges of open joints. A sealed joint protects the edges.

The process

Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours, depending on the length of joint, and the area is left clean. For a village or hamlet like Upstreet, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  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. Edges are cleaned and dried.
  4. A flexible sealant suited to the floor is applied and smooth it.
  5. We check the joints and explain the aftercare.

Preparing for the visit

  • For indoor joints, keep the area dry beforehand if you can
  • Tell us if parking is tricky
  • Mention any sign-in or site rules at work premises

What affects the cost of floor joint sealing

The quote reflects the job in front of us. We look at:

  • How much there is to do
  • Mould in or behind the old joints
  • How many areas need sealing
  • Access and height

Every job is a little different, 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 to tell us for a quote

Photos by email are helpful but not essential. Try to tell us:

  • If it’s domestic, commercial or a hotel
  • Where the job is, and your postcode
  • How we’d reach the joints
  • Whether it has been sealed before

There’s no standard price list, because every job is different. Instead, we send you a clear quote for your job. To get started, call 0345 464 0079 or drop us an email.

Honest limits

It helps to know what we can’t do:

  • Floors that are uneven or need levelling
  • A tiled floor that needs relaying
  • Failed waterproofing under a wet room floor

Questions from Upstreet

Do you work for landlords with property near Sturry station?

Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.

Can you do floor joint sealing in Upstreet?

Yes, Upstreet is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and let us know what needs doing, and we will send you a clear quote.

Do I need to be at home?

That depends on where the joints are. Inside work needs someone to give us access.

Can I choose the sealant colour?

Usually, yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before work begins.

How long does the job take?

That depends on the amount of work, but most jobs take a few hours, depending on the length of joint. We will tell you when we quote.

Why not just use caulk?

Caulk works on still, dry joints, but it splits where the joint moves or gets wet. We use a flexible sealant for most skirting and floor joints.

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 I add another job to the visit?

Yes. More than one area can be quoted together.

New homes and floors in Upstreet

Across Kent, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.

Letting a property close to Sturry station? Then open skirting and floor joints collect dirt and water, so seal them while the property is empty. For site and facilities teams at buildings such as Chislet Church of England Primary School, entrance and corridor floor joints take a lot of traffic. Community buildings like Church of St Mary the Virgin are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.
