About our commercial sealant in Selborne

Mouldy or split sealant in a commercial building causes more than a bad impression. Cleaners struggle with it, water gets through it and people notice it. Our applicators renew sealant across washrooms, welfare areas, kitchens and guest bathrooms. We work on student & care accommodation, welfare facilities and office washrooms & kitchens, and the jobs we see most are washrooms that need sorting before an inspection and mouldy washroom sealant that staff and guests notice.

If you have holiday lets, a converted barn used for business or a community building near Selborne, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

Your job is guaranteed for a year, as with all our work.

Quotes for commercial sealant in Selborne

Some jobs are bigger than they look, and some smaller. The main factors:

  • Any mould that needs treating
  • How much old sealant there is and how hard it is to remove
  • How many rooms, windows or areas are involved
  • The size of the job

Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Helping us quote

To help us quote quickly, let us know:

  • If it’s domestic, commercial or a hotel
  • Any previous sealing or DIY work
  • Roughly how big the job is
  • What’s wrong with the joints now

Getting a quote is simple: tell us what needs doing and where. A few photos by email make the job easier to understand.

Landlord and commercial work in Selborne

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

How to look after the new joints

Aftercare is simple:

  • Use mild cleaners on sealant, not bleach or abrasives
  • Keep a record of which rooms were resealed and when
  • Leave squeegees in busy showers
  • Plan resealing around quiet periods

Make it easy for staff to flag a failing joint. A small gap caught quickly is a short fix.

Water from a failed shower seal can travel: through floors, into ceilings and across into corridors. Early resealing keeps it from getting that far.

Do you work for landlords with property near Alton station?

Yes. We work for landlords and letting agents as well as householders. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.

Is Selborne within the area you cover?

Yes. Selborne is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Are you ARBOMaster approved?

Where is Mr Mastic based?

How long does commercial sealant take?

A typical job takes a morning for a small washroom, and a planned programme for bigger sites, including preparation and clearing up. Your quote will say how long we expect yours to take.

What do you need from me for a quote?

Tell us what needs doing and where, plus photos if you have them. We’ll ask anything else we need to know.

Should I try DIY first?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Can you do several jobs on one visit?

Yes, and it often makes sense. Combining jobs makes good use of the visit.

When to call us in Selborne

A rushed reseal between guests rarely lasts. Sealing over old silicone, sealing wet joints or using the wrong product means the joint fails again soon.

The most common problems we see are:

  • Repeated reseals that don’t last
  • Joints that need doing before an inspection or audit
  • Worktop sealant that has shrunk and stained
  • Whole floors of tired en suites

Schools such as Selborne Church of England Primary School are buildings too, and busy washrooms and kitchens can be resealed in phases so they stay open.

Questions to ask before booking

  • What preparation is included
  • When the joint can take water or movement
  • Whether they seal over old material or remove it
  • How the colour is chosen

Choosing a sealant specialist

Workplaces and buildings in Selborne

Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

Community buildings like Church of St Mary are part of the picture too: halls and community kitchens see heavy use, and their sealant shows it. For landlords with property near Alton station, sealant work can be quoted for a single flat or a whole portfolio.

What we do, step by step

Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes a morning for a small washroom, and a planned programme for bigger sites. In a small place like Selborne, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We start by looking at the rooms and agreeing what’s needed.
  2. Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
  3. Each area is protected and stripped of old sealant.
  4. Once dry, every joint is resealed and tooled.
  5. We let your team know the cure time for every area.

How to prepare

  • Try not to wet indoor joints just before the visit
  • Mention any tricky access
  • Let us know about parking restrictions

DIY sealant or a professional job?

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
