When to call us in Aldworth

In office kitchens and tea points, joints are wet and wiped all day, and grease and cleaning sprays break down sealant. Worktop and sink joints are often the first to go.

People usually contact us when they notice one of these:

  • Mouldy bathrooms flagged at a tenancy check
  • Worktop sealant that has shrunk and stained
  • Silicone laid over old silicone by a previous contractor
  • Washrooms that need sorting before an inspection

Rented homes near Goring & Streatley station change hands often, and sealant work can be quoted for a single flat or a whole portfolio.

Questions to ask before booking

  • Whether the sealant suits the joint
  • What insurance they hold
  • Whether you can choose the colour
  • How long the guarantee is

Choosing a sealant specialist

Commercial sealant for homes and businesses in Aldworth

Office kitchens, staff washrooms and welfare facilities need to be usable every working day. We can plan the work for early mornings or out of hours to keep disruption down. Each area is handed back with its cure time. We work on office washrooms & kitchens, hotel bathrooms and welfare facilities, and people most often call us about mouldy bathrooms flagged at a tenancy check and failed joints in office kitchens and tea points.

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

We stand behind the work with a one-year guarantee.

The process

Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a morning for a small washroom, and a planned programme for bigger sites. Somewhere as small as Aldworth, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We start with a site walk to agree the rooms and the timing.
  2. Every area is sheeted and the old silicone stripped out.
  3. Joints are cleaned, treated for mould and dried.
  4. We lay the right sealant for each area, with anti-fungal silicone in wet rooms.
  5. Rooms are checked and returned with a cure time so staff know when to use them.

Before we arrive

  • Let us know if you’ve seen damp or leaks
  • Let us know about earlier repairs to the joints
  • Mention any parking rules near the property

Aftercare tips

After the cure time, these simple habits help:

  • Keep strong chemicals and scourers off the joints
  • Pass on the cure time to whoever cleans the rooms
  • Include the silicone on your room checklists
  • Plan resealing around quiet periods

Strong chemicals and scourers wear silicone out faster. A mild cleaner and a soft cloth is enough for the joints, with stronger products kept off the bead.

In a commercial building, a leak can quickly spread beyond one room: through floors, into ceilings and across into corridors. Dealing with the joint early stops that spread.

DIY versus a professional finish

If you’ve already had a go yourself, that’s fine. We cut it out and start again.

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.

Workplaces and buildings in Aldworth

Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.

For buildings such as St Mary's church, any kitchen and washrooms need the same sealant care as any other building. For site and facilities teams at buildings such as The Downs School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.

Aldworth: your questions answered

Will you come out to Aldworth?

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

Can you help a landlord with a rental near Goring & Streatley 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 quote.

Can you do several jobs on one visit?

Yes. More than one area can be quoted together.

Will there be a smell?

There can be a smell while the sealant cures, but it fades. Ventilation helps.

How much does commercial sealant cost in Aldworth?

The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we will talk you through it.

Is it worth trying it myself?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.

Will the old sealant be removed?

Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

Can you work around guests in a hotel?

Usually, yes. The order and timing are agreed with your team, and you will know when each room can be used.

How the job changes by surface

Welfare facilities

Shower rooms in welfare blocks get heavy use and need sound joints. We reseal with anti-fungal sanitary silicone.

Hotel bathrooms

We can plan around check-out and check-in times.

What affects the quote in Aldworth

The price is agreed before any work begins. It takes into account:

  • The number and length of the joints
  • Mould in or behind the old joints
  • When we can work, for business premises
  • The old material and how stubborn it is

Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.

  • Whether it’s a home or a business
  • If someone has resealed it before
  • The address or postcode of the job
  • The problem you’ve noticed

Getting a quote is simple: let us know what needs doing and where. Photos by email help us understand the job, and we’ll take it from there.
