What affects the quote in Frogmore

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

  • The number and length of the joints
  • How much old sealant there is and how hard it is to remove
  • Whether there’s mould to deal with
  • How many areas need sealing

There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

What we need to know

You do not need to know the technical terms. Just tell us:

  • Roughly how big the job is
  • Whether it has been sealed before
  • If it’s domestic, commercial or a hotel
  • What’s wrong with the joints now

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.

About our floor joint sealing in Frogmore

A threshold joint has to cope with feet, movement and sometimes water. We use a flexible product that suits both floors so the joint stays neat. Common call-outs are for skirting caulk that keeps splitting and skirting that has pulled away from the floor, on concrete floor joints, thresholds and tiled floors.

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

You’re covered for a year from the day we finish. If anything is not right with it, phone 0345 464 0079 or email us.

Signs you need floor joint sealing in Frogmore

Timber floors and skirting shrink and swell through the year. Heating dries timber and opens gaps along the skirting, then close again in damper months.

Look out for these signs:

  • Tiled floors with no room to move
  • Dirt and water collecting in open floor joints
  • Gaps opening between the floor and skirting
  • Failed seals where bathroom floors meet baths and panels

Letting a property close to How Wood station? Then gaps at skirtings and thresholds are worth sealing between tenancies.

10 questions to ask before booking

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.

Thresholds

Thresholds between rooms meet two floors and often a door frame. A flexible sealant suits both floor finishes.

What we do, step by step

We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a morning or an afternoon for most homes and we leave things clean and tidy. For a village or hamlet like Frogmore, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. 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. Old caulk, grout or sealant is removed from the joint.
  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

  • Keep children and pets away from the work area
  • Mention any parking rules near the property
  • Tell us about any water getting in

What floor joint sealing looks like in Frogmore

Across Hertfordshire, 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.

Managing a site like Park Street Church of England Voluntary Aided Primary School? Then entrance and corridor floor joints take a lot of traffic. Community buildings like Church of the Holy Trinity are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.

Common questions in Frogmore

Is Frogmore within the area you cover?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you work for landlords with property near How Wood station?

Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.

Can you do several jobs on one visit?

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

Is the work guaranteed?

Yes, always. There’s a 12-month guarantee on every job, wherever you are.

Will I be able to paint over the new joint?

On joints you want to paint, yes. Silicone doesn’t take paint, so tell us your plans.

Why does the gap under my skirting keep coming back?

Floors and walls move a little with the seasons, and new floors settle. A flexible sealant closes the gap without cracking like caulk.

Do you hold any approvals?

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

Can you reseal concrete floor joints in an industrial unit?

Yes. We reseal concrete floor joints in commercial and industrial units. The product is chosen for the traffic the floor takes.

Keeping the joints in good condition

How long the joints last depends on use and care. Here’s what we suggest:

  • Avoid sloshing water against skirting
  • Get cracks along tile grout lines looked at early
  • Ask before painting over a sealed joint
  • Use furniture pads near skirting

Keep heavy traffic off resealed concrete joints for the cure time we give you. Mark the area off so drivers avoid it while it cures.

Once concrete joint edges start to break, wheels make it worse. Early resealing helps keep the joint intact and the floor safer.
