Landlord and trade work in St Nicholas

We work for landlords, letting agents and housing providers in St Nicholas as well as homeowners. Repairing between tenancies keeps void periods short, and it costs much less than replacing.

For anyone letting property in or around St Nicholas, we’ll quote for several properties at once. Send pictures for each one and we’ll price them together.

DIY kit or professional repair?

It’s tempting to reach for a kit, but many of the jobs we do start with putting right a DIY repair. Doing it properly first is typically the cheaper route.

What a professional repair adds is preparation, colour matching and finishing. We clean and key the area properly, mix the colour to your surface and finish it to the same sheen, and the work is guaranteed.

Should you replace it?

A new window, door or sill costs far more, and it may not match the rest after years of weathering. A repair leaves the unit in place. Our uPVC repair starts from £95. Every job is a little different, so we price each one individually. The size and type of damage, the material and access all play a part, and doing several things on one visit costs less than separate visits.

Why us?

  • Every repair guaranteed for a year
  • Nothing taken out or refitted
  • A fixed quote before booking
  • Repair technicians who travel to you, UK-wide

What uPVC repair costs

Prices start from £95. Prices are worked out job by job, from your photos. The main factors are:

  • The material and finish
  • Doing more than one item at once
  • Whether old repairs or coatings need taking off
  • The size and number of damaged areas

We charge the same wherever you are, so there is no premium for St Nicholas. What changes the price is the job itself: the material, the amount of damage and how many items.

Getting a price from pictures

You can usually get a fixed quote without us visiting. To help us price it:

  • A close-up of the damage, in focus
  • A coin or ruler next to the damage for scale
  • Your postcode, so we can check dates
  • The material, if you know it

Getting a price is easy: snap the damage close up and then the whole item, send them to us with your postcode, and we will reply with a fixed quote. There’s no charge for the quote and you’re under no obligation.

Questions from St Nicholas

Can you repair something that is been repaired before?

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

Do you cover the whole of Cardiff?

We cover the whole UK, including St Nicholas and the rest of Cardiff. Send your postcode with your photos and we’ll confirm dates.

Is it worth repairing rather than replacing?

Generally, yes. A repair skips the removal, fitting and redecorating. We’ll be honest if it’s not worth it.

How soon can you come?

Your quote comes with available dates. Tell us if you need it done quickly.

What happens next?

We review the pictures and send a fixed quote.

Is there a guarantee?

Yes: twelve months. If anything goes wrong with the repair within the year, we return to fix it.

Can pets and children be at home?

Yes, as long as they stay out of the room we are working in. We’ll tell you when the room can be used again.

Are you accredited?

Yes, including CHAS, Constructionline and SafeContractor. The full list is on our accreditations page.

Honest limits

Some jobs aren’t right for a repair, including:

  • Failed or misted double glazing units
  • Broken locks, hinges or mechanisms
  • Frames that are warped or out of square

Send us photos and we’ll tell you honestly.

What we work on

  • Doors & door panels
  • White uPVC
  • Window frames & sills
  • Coloured and woodgrain uPVC
  • Conservatory frames

What we do, step by step

On the day itself, there’s little for you to do. Let us in and show us the room, and we will take it from there. Most visits take a few hours, including clearing up.

  1. First the frame or panel is cleaned.
  2. Next we fill the damage.
  3. The repair is sanded smooth.
  4. We colour-match the finish, including woodgrain effects.
  5. We blend the repair into the surrounding surface.

Getting ready for the visit

  • Let us know about parking or access
  • Let the surface dry out before the visit
  • Have somewhere for us to park nearby if possible

Ask for a price

Email us pictures of the damage and a wider shot of the entire item, and tell us you are in St Nicholas, and we will reply with a fixed price.
