Floor joint sealing near Ashwell

Floor joint sealing in Ashwell

Floor joint sealing is mostly about choosing the right product and preparing the joint. We remove what’s there first, then clean, back and seal the joint. Typical jobs include perimeter joints in tiled floors filled with grout and chipped and open joints in warehouse floors, on concrete floor joints, thresholds and commercial floors.

Homes around Ashwell range from older cottages to newer houses, and their floors range just as widely, from timber that moves with the seasons to tiles laid on concrete. The sealant at skirtings and thresholds has to suit the floor it meets.

Each job carries a 12-month guarantee, large or small.

Why act early in Ashwell

Regrouting a cracked line in a tiled floor rarely fixes it. The movement is still there, so the grout fails again. A flexible movement joint is the fix. In a smaller place like Ashwell, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.

Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Why book with us

  • A choice of colours where the product allows
  • Anti-fungal sanitary silicone in wet areas
  • Full insurance on every job
  • Neat joints and a tidy finish

DIY sealant or a professional job?

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

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

What affects the quote in Ashwell

For a quick quote, just ask. What matters most is:

  • Whether the work is at height
  • How many areas need sealing
  • Whether old sealant or filler has to be cut out
  • Mould in or behind the old joints

Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

Joints and finishes in Ashwell homes

Across Hertfordshire, 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.

For landlords with property near Ashwell & Morden station, gaps at skirtings and thresholds are worth sealing between tenancies. For buildings such as St Mary's Church, floor and skirting joints in halls and kitchens wear like any others.

Signs you need floor joint sealing in Ashwell

Timber floors and skirting shrink and swell through the year. Heating dries timber and opens gaps along the skirting and they change again in summer.

The most common problems we see are:

  • Dirt and water collecting in open floor joints
  • Grout cracking in a straight line across a floor
  • Skirting that has pulled away from the floor
  • Failed joint filler in concrete floors

Managing a site like Ashwell Primary School? Then floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

10 questions to ask before booking

Questions from Ashwell

Will you come out to Ashwell?

Yes, Ashwell is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

I let a flat near Ashwell & Morden station. Can you help?

Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.

Do I have to be there?

Access is agreed with you when the job is booked. For inside work, that normally means someone being in.

Is there any odour?

It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.

Will you leave a mess?

Not at all. We work neatly, protect the area around the joints and tidy up afterwards.

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

Often, yes. We replace the grout along a suitable line with flexible sealant coloured to suit. If tiles are loose, that needs fixing first.

Will the old sealant be removed?

Yes. All of the old material is cut out and the joint cleaned.

Do you have insurance?

Yes. We’re fully insured for domestic and commercial work.

Keeping the joints in good condition

No joint lasts for ever, but care makes a real difference. Our tips:

  • Check skirting joints after the heating season
  • Do not paint over silicone
  • Have a cracking tiled floor checked before tiles break
  • Avoid sloshing water against skirting

Check the joints after the first winter. If anything has opened, it’s easy to reseal.

Small gaps are quick to seal. Ignored, they fill with dirt and open further over time.

What we do, step by step

All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we have agreed what’s being done, we protect the area and start. Most jobs take a morning or an afternoon for most homes. In a smaller place like Ashwell, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.

  1. We start by checking the floor, the joint and what traffic it takes.
  2. We remove what’s in the joint now.
  3. We vacuum out the joint and add backing where the depth needs setting.
  4. The chosen sealant goes in, coloured to suit the floor.
  5. We tool it neatly and tell you when it can be walked on and cleaned.

How to prepare

  • Let us know about earlier repairs to the joints
  • Tell us about any water getting in
  • Where the joints are inside, avoid wetting them before we arrive
