Questions from Watford

Will the price change on the day?

If we find something the pictures didn’t show, we explain it first. The price only changes if you agree.

Can you price it without visiting?

Normally, yes. Clear pictures let us give you a fixed quote without visiting.

Do you come to Watford?

We do. We send a technician to Watford for every job, and the price is the same as everywhere else.

Which areas do you work in?

Everywhere in the UK, Watford included. There’s no extra charge for travel.

Is a repair better than a new one?

Usually, when the rest is in good condition. Repairing avoids the cost and disruption of replacing. If replacing would be better, we’ll say so.

How long does resealing take?

A bath or shower typically takes a couple of hours. Leave it to cure before use.

Can I add another job to the visit?

Of course, and it usually saves money. Just add the extra items to your photos and you’ll get one combined price.

It’s been repaired before. Can you still fix it?

Yes, regularly. It can add a little time, which we include in the quote.

Bath resealing in Watford, done in place

We reseal baths with them filled with water, so the joint is at its widest, so the seal does not tear when the bath is first used. Our technicians work on basins & vanity units, baths and shower trays & enclosures, and common reasons people contact us are discoloured, yellow sealant and gaps in the seal.

You’re covered after we leave: each job carries a one-year guarantee, and we will explain exactly what it covers when we quote.

How it works

Once we’re through the door, we keep the work contained to the one room. We mask off everything nearby, the job takes a couple of hours, and we finish with a tidy-up and a look at the finished work together.

  1. We protect the area and mask the joint lines.
  2. Old sealant and residue are removed.
  3. The joint is cleaned, treated and dried.
  4. Fresh silicone is applied in a continuous bead.
  5. We smooth the bead, remove the tape and leave it to cure.

Getting ready for the visit

  • Make sure the area is dry
  • Open a window if you can
  • Let us know if it has been repaired before

Common problems we fix in Watford

In time, even good sealant discolours. Steam, soap and movement all wear it down.

Customers usually contact us about:

  • A messy previous reseal
  • Water getting behind the bath or tray
  • Old sealant that looks dirty
  • Missing sealant behind the taps

Questions to ask before you book

  • Who will actually do the work
  • How to care for the finish
  • How your room will be protected
  • How the colour is matched

Prices and what affects them

We give every job a fixed price from photos. This is what makes a difference:

  • How much damage there is
  • Whether old repairs or coatings need taking off
  • What kind of damage it is
  • Doing more than one item at once

We charge the same wherever you are, so there is no premium for Watford. What changes the price is the job itself: how much damage, what it’s made of and how many items.

How to get a fixed price

A couple of clear pictures is all it takes. It helps if you send:

  • Whether it’s been repaired or coated before
  • What it’s made of, if you know
  • Something in shot to show the size
  • Where you are, by postcode

Email us pictures of the damage and a wider shot of the entire item, with your NN6 postcode, and we’ll reply with a fixed quote.

Honest limits

We’ll always be straight with you, so here’s what a repair will not do:

  • Tiles that move, until they’re refixed
  • Very wide gaps that need a trim
  • Water damage behind the bath that needs a builder

Not sure? Send photos and we will give you a straight answer.

Materials we work on in Watford

  • Wet rooms
  • Shower trays & enclosures
  • Basins & vanity units
  • Kitchen worktops & sinks
  • Baths

Why reseal now?

Putting new silicone over old does not last. It soon peels, and traps mould underneath. A proper reseal removes the old first. A repair typically costs much less than people expect, particularly next to the cost of replacement. Send photos and we will give you the exact figure.

Landlord and trade work in Watford

Letting agents frequently send us photos straight from the inventory. That means we can quote before you even visit the property, and we can arrange access with the tenant directly if that helps.

Housing associations and facilities teams use us for planned and reactive repairs. A repair avoids taking out and refitting, which matters when someone is living in the home.

Repairs by material

Baths

Baths are resealed with water in them, to open the joint fully.

Shower trays

We put weight on a tray before sealing it, so the joint is at its widest.

DIY repairs versus a professional job

A DIY attempt isn’t a disaster. We remove the old filler and start again, so it doesn’t stop a professional repair. Just mention it when you send pictures, as it can add time.

The difference between a kit and a professional repair is mostly in the preparation and colour. We prepare the area properly, mix the colour on site and polish the finish to match, then guarantee it for a year.
