Landlords, agents and businesses in Twynyrodyn

Letting agents often send us photos straight from the inventory. You can have a price before you arrange access, and we can arrange access with the tenant directly if that helps.

Builders use us to fix snagging damage before handover. We can visit several plots in one trip to keep costs down.

DIY repairs versus a professional job

What a professional repair adds is preparation, colour matching and finishing. We prepare the area properly, mix the colour on site and polish the finish to match, and the work is guaranteed.

A kit can be fine for a tiny mark out of sight. For anything you look at every day, anything that has rusted, cracked or holed, or anything on a coloured surface, it’s worth having it done properly.

Questions from Twynyrodyn

Is it OK to have pets in the house?

Please keep children and pets out of the room during the visit. The rest of the house is unaffected.

How do I stop mould in sealant?

Normally poor ventilation and moisture sitting on the joint. Mould-resistant silicone and good ventilation help.

What happens once I’ve sent pictures?

We come back with a fixed quote, plus dates. You’re under no obligation.

Are you a vetted contractor?

We hold CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile accreditations.

My seal keeps tearing. Why?

Movement is the usual cause, or it was sealed with the bath empty. We seal baths full of water.

Do the materials smell?

There can be some smell while we work. It clears as the materials cure.

When can I use the bath after resealing?

Normally about a day later. We will tell you the exact time.

What do you need from me?

Some photos, your postcode and how to reach you. On the day, we only need access to the room.

Keeping it looking good

Simple care helps the repair last. Our advice:

  • Keep the joints dry
  • Replace the seal when mould sets in
  • Clean the sealant gently and regularly
  • Use the extractor fan

Keep the room well ventilated, and wipe the joints after use.

Black mould in sealant isn’t just unsightly, it’s a sign moisture is sitting in the joint. Resealing early keeps water out of the walls and floor.

The process

There is not much you need to do on the day. Show us the job, point us to the room, and we’ll take it from there. Most visits take a couple of hours, tidy-up included.

  1. We cut out all of the old sealant.
  2. We remove the residue and clean the joint.
  3. Any mould is treated and the joint dried.
  4. We fill the bath, or weight the tray, to open the joint.
  5. We apply fresh mould-resistant silicone and tool a neat bead.

Preparing for the visit

  • Let the surface dry out before the visit
  • Plan for the room to be out of bounds to pets and children
  • Point us to the nearest place to park
