Floor joint sealing for homes and businesses in Highclere

Tiled floors can crack along the grout when there’s no room for movement. Where one is needed, we rake out the grout along the right line and replace it with flexible sealant. We work on tiled floors, commercial floors and concrete floor joints, and the jobs we see most are worn sealant at door thresholds and rigid edge joints in tiled floors.

Older homes in small places like Highclere often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.

Each job carries a 12-month guarantee.

What happens on the day

Before we leave, we go over the finished joints with you. The visit itself usually takes a few hours for most rooms, longer for large commercial floors, depending on the size of the job. Somewhere as small as Highclere, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We clear the edges of the floor so the joints are easy to reach.
  2. We take out the cracked caulk, grout or old sealant.
  3. We clean and dry the edges of the joint.
  4. We apply a flexible sealant suited to the floor and tooled.
  5. Finally, we check the work and talk you through aftercare.

How to prepare

  • Mention any tricky access
  • Mention any leaks or damp you’ve noticed
  • Plan for the work area to be out of bounds to pets and children

DIY versus a professional finish

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

Signs you need floor joint sealing in Highclere

Wheels crossing an unfilled concrete joint chip its edges. Hard wheels damage the joint edges and the joint gets wider.

Any of these means the joints need attention:

  • Gaps opening between the floor and skirting
  • Gaps at thresholds between rooms
  • Rigid edge joints in tiled floors
  • Cracked grout where a tiled floor needs a movement joint

For site and facilities teams at buildings such as Woolton Hill Junior School, entrance and corridor floor joints take a lot of traffic.

Questions to ask before booking

  • What guarantee comes with the work
  • How the surfaces are prepared before sealing
  • Whether the sealant suits the joint

10 questions to ask before booking

Why act early in Highclere

The right product depends on the floor and the traffic: skirting and tiled floors need flexibility, wet areas need water resistance and concrete needs a product suited to wheels. Using the wrong one is why many floor joints fail. In a small place like Highclere, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will explain what it covers.

Highclere questions

Do you cover smaller places like Highclere?

Yes, Highclere is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

I let a flat near Newbury station. Can you help?

Yes, we work for landlords and agents. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.

Can I add another job to the visit?

Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

Do you offer different sealant colours?

In most cases you can choose. We’ll tell you which colours the right product comes in.

Can new sealant go over the old?

No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.

Will I be able to paint over the new joint?

For painted skirting, we use a flexible product that can be painted. Silicone will not take paint, so it’s kept for wet areas and unpainted joints.

Where is Mr Mastic based?

We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.

My floor grout keeps cracking in a line. Can you help?

Often, yes. Straight cracks in grout often show where a movement joint was needed. We rake out that line and seal it with flexible sealant.

When something else is needed

Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:

  • Concrete repairs beyond the joint
  • Large cracks that need a surveyor
  • Floors that are uneven or need levelling

If you’re not sure, just call 0345 464 0079 or email us and we will give you a straight answer before you book.

What we seal

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

What floor joint sealing looks like in Highclere

Across West Berkshire, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and they do not all move the same way. The joint at the skirting or threshold has to allow for that.

Letting a property close to Newbury station? Then gaps at skirtings and thresholds are worth sealing between tenancies. For buildings such as Church of St Michael Archangel, floor and skirting joints in halls and kitchens wear like any others.

How the job changes by surface

Thresholds

Thresholds between rooms meet two floors and often a door frame. We seal them with a flexible sealant that suits both sides.

Wet room and bathroom floors

Mop water gets into any open joint at the edge of a bathroom floor. A neat silicone joint keeps it out.

Keeping the joints in good condition

Good habits help new joints last longer. A few tips:

  • Lift furniture rather than dragging it across joints
  • Avoid caulk in bathrooms and kitchens
  • Ask before painting over a sealed joint
  • Look at floor joints each spring

Keep heavy traffic off resealed concrete joints for the cure time we give you. Cone off the area if needed.

Once concrete joint edges start to break, wheels make it worse. Sealing them early protects the edges and the surface smoother.
