How we quote for floor joint sealing

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

  • Access and height
  • Any mould that needs treating
  • How many rooms, windows or areas are involved
  • Which sealant suits the joint

What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before work begins.

Asking for a quote

To make quoting easier, let us know:

  • A few photos by email, if you can
  • Roughly how big the job is
  • If someone has resealed it before
  • Whether it’s a home or a business

Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we’ll explain what’s involved before giving you a price.

Floor joint sealing in Thorney

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. Common call-outs are for failed seals where bathroom floors meet baths and panels and caulk that has cracked where the floor moves, across skirting boards, concrete floor joints and commercial floors.

For a small place like Thorney, the journey and access are planned in advance, and once on site, the job is the same as anywhere.

Whatever the size of the job, you get the same 12-month guarantee in Thorney and across Buckinghamshire.

Floor joint sealing in Thorney: local notes

Across Buckinghamshire, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. That’s why the skirting and threshold joints need a flexible seal.

For site and facilities teams at buildings such as St Catherine Catholic Primary School, floor and threshold joints in busy corridors wear quickly and are best resealed early. Letting a property close to Iver station? Then gaps at skirtings and thresholds are worth sealing between tenancies.

Why deal with it now?

Waiting until the next redecoration can mean a winter of draughts and dirt in the gaps. It’s a quick job to seal them now. Older cottages and farmhouses around Thorney can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What you get with us

  • Approved under the ARBOMaster scheme
  • Colour agreed with you before work begins
  • Rated 4.9 stars on Google
  • White, clear, grey or coloured to suit, where the product allows

Should I try it myself first?

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.

Questions from Thorney

Can you help a landlord with a rental near Iver station?

Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.

Do you cover Thorney for floor joint sealing?

Yes. Our work covers London and the South East, and Thorney is part of that. Just call 0345 464 0079 or email us with a few details of the job.

Can I choose the sealant colour?

We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.

Do you use a paintable sealant?

For painted skirting, we use a flexible product that can be painted. Silicone isn’t made to be painted, so it’s kept for wet areas and unpainted joints.

Does someone need to be in?

If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.

Can I do it myself?

You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.

Do you guarantee your work?

Yes, for a year. If anything is not right with the work within the year, let us know and we will sort it.

How do I get a quote for floor joint sealing in Thorney?

We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before we start.

The process

You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes a few hours, depending on the length of joint for a typical job. Somewhere as small as Thorney, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We look at the gap and the floor type and agree the right sealant.
  2. We take out any old caulk, sealant or grout along the line.
  3. The joint is cleaned, vacuumed and backed where depth needs controlling.
  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.

Getting ready for the visit

  • Try not to wet indoor joints just before the visit
  • Keep pets and children clear of the area while we work
  • Mention if the joints have been sealed before

When to call us in Thorney

Water and dirt collect in open floor joints. In wet areas, water runs into the gap at every clean and can reach the subfloor.

It’s worth asking for a quote if you see:

  • Open joints around bathroom floor edges
  • Open gaps along the bottom of skirting boards
  • Grout cracking in a straight line across a floor
  • Concrete floor joints that have broken down

Community buildings like St. Leonard's are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.

What to look for in a quote

  • Which sealant they’ll use, and why
  • What preparation is included
  • Are they insured?
  • How long the guarantee is
