What we do, step by step

Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes anything from a few hours to several days, depending on the number of rooms, depending on how much there is to do. In a smaller place like Welham Green, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.

  1. We start by looking at the rooms and agreeing what’s needed.
  2. We agree when we’ll work, with early or out-of-hours slots where they can be arranged.
  3. Each area is protected and stripped of old sealant.
  4. Joints are dried, then resealed and tooled neatly.
  5. We let your team know the cure time for every area.

Getting ready for the visit

  • Keep children and pets away from the work area
  • Let us know about parking restrictions

Advice

Do you need commercial sealant in Welham Green?

A hotel shower or office washroom is used many times a day, and they’re cleaned with strong products every day. That’s why sealant fails sooner.

Keep an eye out for any of the following:

  • Large numbers of bathrooms needing the same work
  • Black, stained silicone in guest bathrooms
  • Washrooms that need sorting before an inspection
  • Split sealant where wet room floors meet walls

Rented homes near Welham Green station change hands often, and several rental properties can be resealed on one programme.

Choosing a sealant specialist

When something else is needed

A few problems are outside what sealant work can do:

  • Leaking pipework, valves or wastes (a plumber’s job)
  • Poor ventilation that keeps bringing mould back
  • A shower tray, bath or basin that is cracked or broken

If you’re not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer.

Surfaces we seal

  • Retail & leisure sites
  • Hotel bathrooms
  • Welfare facilities
  • Rental portfolios
  • Student & care accommodation
  • Office washrooms & kitchens

Should I try it myself first?

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.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

Different surfaces, different methods

Rental portfolios

Landlords and agents can have several properties resealed in one programme.

Retail & leisure sites

Gym and leisure changing rooms take heavy use and plenty of water, so anti-fungal sanitary silicone is the product we use.

What commercial sealant looks like in Welham Green

Welham Green is part of Hatfield, one of the post-war new towns. Like the other new towns, Hatfield was planned with its own areas for industry and business, so workplaces sit close to the homes. Their washrooms, kitchens and fire-rated joints need the same upkeep as anywhere. Welham Green has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.

If you look after a building such as St Mary's Church of England Primary School, busy washrooms and kitchens can be resealed in phases so they stay open. Community buildings like Church of St Mary the Virgin are part of the picture too: halls and community kitchens see heavy use, and their sealant shows it.

Welham Green: your questions answered

I let a flat near Welham Green station. Can you help?

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

Is Welham Green within the area you cover?

Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Do you take out the old sealant first?

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

Can you seal over the old sealant?

No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.

Can you take on a whole building?

Yes. We will walk the site, agree the scope and the order, and give you one clear quote.

Which products do you use?

It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

Can I do it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

How long does the job take?

It depends on the size of the job, but most jobs take a morning for a small washroom, and a planned programme for bigger sites. We’ll give you a better idea when we quote.

Looking after it afterwards

How long the joints last depends on use and care. Here’s what we suggest:

  • Tell cleaning staff when each room can be used
  • Get split or lifting joints looked at early
  • Ask cleaners to go gently on the silicone
  • Plan resealing around quiet periods

Daily cleaning with harsh chemicals shortens the life of any sealant. A mild cleaner and a soft cloth is enough for the joints, with stronger products kept off the bead.

Watch for the warning signs: mould, splits, peeling corners or water marks downstairs. When you see them, it’s time to plan a reseal.
