Floor joint sealing for Newnham homes and businesses

Joints and finishes in Newnham homes

Floors around Hertfordshire run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. That is why the skirting and threshold joints need a flexible seal.

If you look after a building such as The Knights Templar School, floor and threshold joints in busy corridors wear quickly and are best resealed early. Community buildings like Church of St Vincent are part of the picture too: floor and skirting joints in halls and kitchens wear like any others. Letting a property close to Baldock station? Then a tidy floor and skirting joint helps a rental look ready for the next tenant.

Floor joint sealing for homes and businesses in Newnham

Large tiled floors, and those over underfloor heating, often need movement joints. We can turn a line of grout into a movement joint by replacing it with flexible sealant. Common call-outs are for open gaps along the bottom of skirting boards and caulk that has cracked where the floor moves, across concrete floor joints, wet room & bathroom floors and skirting boards.

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

The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or drop us an email.

Surface by surface

Concrete floor joints

We clean concrete joints out thoroughly before sealing first. Backing goes in where the depth needs controlling.

Tiled floors

Perimeter joints in tiled floors should be sealant, not grout. Grout at the edge is removed and replaced with sealant.

DIY sealant or a professional job?

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 does not work out, we can still put it right.

What affects the cost of floor joint sealing

For a quick quote, just ask. The main things that affect it are:

  • Access and height
  • Whether old sealant or filler has to be cut out
  • How many rooms, windows or areas are involved
  • Which sealant suits the joint

Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will go through it with you.

Asking for a quote

When you call or email, it’s useful to know:

  • Where the property is
  • If it’s domestic, commercial or a hotel
  • Roughly how big the job is
  • Access, such as stairs, a lift or height

For a quote, phone 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. You will have a clear quote before work begins.

Landlord and commercial work in Newnham

Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.

What we do, step by step

Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most rooms, longer for large commercial floors. Somewhere like Newnham needs a little journey planning: 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. First, the floor type, the gap and the traffic are checked.
  2. Any old caulk, grout or sealant is raked or cut out.
  3. The joint is vacuumed clean and backing fitted where needed.
  4. We apply the sealant in a colour that suits the floor.
  5. We tool it neatly and tell you when it can be walked on and cleaned.

Preparing for the visit

  • Keep pets and children clear of the area while we work
  • Mention any tricky access
  • Mention if the joints have been sealed before

Why it’s worth doing now in Newnham

Regrouting a cracked line in a tiled floor rarely fixes it. If the floor needs to move there, the grout will crack again. A flexible movement joint is the fix. In a small place like Newnham, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

Why us?

  • A sealant colour to suit the surroundings
  • You choose the colour before work begins
  • A choice of colours where the product allows

Newnham questions

Is Newnham within the area you cover?

Yes, Newnham is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

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

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.

Can you reseal concrete floor joints in an industrial unit?

Yes. Old filler is cleaned out and the joint resealed with a floor-joint product. Tell us what runs over the floor.

Do you guarantee your work?

Yes, always. Each job is guaranteed for twelve months.

Do I have to be there?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Will I be able to paint over the new joint?

Where you plan to paint, we do. Silicone doesn’t take paint so mention it when you get a quote.

What do you need from me for a quote?

Let us know what needs doing and where, with pictures by email if possible. We will ask anything else we need to know.

Is it worth trying it myself?

That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.

Looking after it afterwards

A little care helps the new joints last. We recommend:

  • Check skirting joints after the heating season
  • Ask before painting over a sealed joint
  • Act on grout cracks that run in a straight line
  • Sweep along the edges of the floor

In commercial units, keep pallet trucks and heavy wheels off new joints until they’ve cured. Mark the area off so drivers avoid it while it cures.

Open skirting gaps let in draughts, dust and sometimes insects. Sealing it keeps the room tidier.
