New homes and floors in Hilsea

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

For buildings such as St Francis' Church, floor and skirting joints in halls and kitchens wear like any others. For site and facilities teams at buildings such as Gatcombe Park Primary School, entrance and corridor floor joints take a lot of traffic. If you let a flat or house near Hilsea station, a tidy floor and skirting joint helps a rental look ready for the next tenant.

What affects the quote in Hilsea

We quote each job individually. These are the things that affect it:

  • The number of rooms or windows
  • Mould in or behind the old joints
  • When we can work, for business premises
  • The type of sealant required

Instead of a standard rate, 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 by email are helpful but not essential. Try to tell us:

  • Any access issues, like height or stairs
  • Whether it has been sealed before
  • What the problem is, such as mould, gaps, leaks or cracking
  • If it’s domestic, commercial or a hotel

Getting a quote is simple: tell us what needs doing and where. A few photos by email make the job easier to understand, and we’ll come back to you with a quote.

Looking after it afterwards

Good habits help new joints last longer. Our tips:

  • Have a cracking tiled floor checked before tiles break
  • Don’t slide heavy items over sealed joints
  • Keep dirt out of the joints
  • Don’t paint over silicone

Silicone sealant isn’t made to take paint. If the joint will be painted, tell us beforehand so we use a paintable sealant.

A gap under the skirting collects dust and lets draughts through. Sealing it keeps the room tidier and stops it getting worse.

Landlord and commercial work in Hilsea

Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

What happens on the day

Every visit runs the same way: we check the joints, protect the area around them, do the work and tidy away. It normally takes a morning or an afternoon for most homes. For a job in Hilsea, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. We start by looking at the floor, the gap and the traffic, then choose the product.
  2. Old caulk, grout or sealant is removed from the joint.
  3. The joint is vacuumed clean, with backing fitted wherever depth matters.
  4. A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
  5. The joint is tooled to a neat finish and we tell you when it can take feet and a mop.

Getting ready for the visit

  • Let us know about parking restrictions
  • Clear the area around the work
  • Mention any sign-in or site rules at work premises

Questions from Hilsea

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

Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.

Is Hilsea in your area for floor joint sealing?

Yes, Hilsea is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear price.

Can you seal where the floor meets the bath panel?

Yes. These joints get wet every time the floor is cleaned, so a flexible silicone is the right choice.

Can you quote for more than one area?

Yes. Just list everything you need.

Will it make a mess?

Tidy work is part of the job. We protect what’s around the joints.

How long does the job take?

A typical job takes a few hours for most rooms, longer for large commercial floors, including preparation and clearing up. Your quote will say how long we expect yours to take.

Is it OK to seal over old sealant?

No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

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

Often, yes, at the edges and along suitable lines. We remove the grout and seal the line with flexible sealant.

Why deal with it now?

Caulk is quick and cheap, but it cracks where the joint moves or gets wet, but the movement soon cracks it. A flexible sealant stretches instead. In a smaller place like Hilsea, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.

We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or email us and we’ll talk you through it.

Different surfaces, different methods

Concrete floor joints

Sawn joints in concrete floors control where it cracks. We reseal them with a floor-joint product suited to the traffic.

Skirting boards

If the skirting is painted, a paintable flexible sealant works well. Where water is involved, silicone is the better choice.

Can I do it myself?

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
