Keeping the joints in good condition

After the cure time, these simple habits help:

  • Walk round the room once a year and look at the edges
  • Use a well-wrung mop rather than flooding the floor
  • Get cracks along tile grout lines looked at early
  • Avoid caulk in bathrooms and kitchens

Check the joints after the first winter. Small gaps at the ends can be touched up early on.

A tiled floor that cracks along a line will keep cracking until it can move. Adding a movement joint early can stop cracks spreading to the tiles.

Floor joint sealing in Holwellbury

In kitchens and bathrooms, the joint where the floor meets a bath panel, plinth or skirting takes mop water every day. A flexible silicone seal keeps it out so water and dirt cannot get in. If you are dealing with perimeter joints in tiled floors filled with grout and open joints around bathroom floor edges, we can help, whatever the surface.

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

We stand behind the work with a 12-month guarantee.

Joints and finishes in Holwellbury homes

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

Managing a site like Derwent Lower School? Then floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. Community buildings like Church of St Peter (C of E) at Corner with Holwell Road are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.

When something else is needed

New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:

  • Water getting under the tiles from elsewhere
  • Structural movement or subsidence
  • A tiled floor that needs relaying

If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think.

What we seal

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

Work for landlords, hotels and businesses

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

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’re called out for in Holwellbury

Some floors were never given a perimeter gap or movement joint. As it expands, the edges lift or crack.

Signs it’s time to call us include:

  • Gaps between floors and kitchen plinths
  • Threshold joints that have opened or worn
  • Perimeter joints in tiled floors filled with grout
  • Dirt and water collecting in open floor joints

Letting a property close to Arlesey station? Then open skirting and floor joints collect dirt and water, so seal them while the property is empty.

What your quote should include

  • Whether the sealant suits the joint
  • How hidden problems are handled
  • Who turns up on the day
  • What the cure time is

How to choose a mastic man

Why act early in Holwellbury

Water that gets past a floor joint can damage the floor beneath. Dealing with it early keeps the repair to the joint. In a small place like Holwellbury, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Holwellbury: your questions answered

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

Yes, we work for landlords and agents. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.

Do you cover smaller places like Holwellbury?

Yes. Holwellbury is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Are you ARBOMaster approved?

Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.

What do you put in the joint?

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

Can you do several jobs on one visit?

Yes. Tell us about everything you’d like done and we’ll quote it together.

Why has a gap opened under my skirting?

Timber floors and skirting shrink and swell through the year. A flexible sealant closes the gap without cracking like caulk.

How long does the job take?

It depends on the size of the job, but most jobs take a morning or an afternoon for most homes. We will give you a better idea when we quote.

Do you seal floor joints in bathrooms and kitchens?

Yes. These joints get wet every time the floor is cleaned, so we seal them with silicone suited to wet areas.

What affects the cost of floor joint sealing

Every job gets its own quote. This is what makes a difference:

  • Whether old sealant or filler has to be cut out
  • The size of the job
  • When we can work, for business premises
  • How many rooms, windows or areas are involved

Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Asking for a quote

Photos help, but a description is a good start. Try to tell us:

  • The problem you’ve noticed
  • If someone has resealed it before
  • How many joints, rooms or windows are involved
  • Whether it’s a home or a business

Every job is quoted individually, so start by telling us what you need. Simply ring 0345 464 0079 or send us an email and describe the job.

What we do, step by step

Before we leave, we go over the finished joints with you and explain the cure time. The visit itself usually takes a morning or an afternoon for most homes, depending on the amount of work. In a small place like Holwellbury, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First, the floor type, the gap and the traffic are checked.
  2. We remove what’s in the joint now.
  3. The joint is vacuumed clean and backing fitted where needed.
  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.

Preparing for the visit

  • Tell us about any previous sealing or DIY attempts
  • Mention any tricky access
  • Tell us if parking is tricky
