## In customers' own words
_Verbatim quotes from this trader's public reviews, each attributed to its source:_
> "P Marczac Builders carried out some work on my kitchen. The works included demolishing existing kitchen units, levelling and tiling of floor, preparing and painting of walls, as well as tiling sections of the walls. There was also a complete rewiring of the kitchen and fitting of a new fuse box. The work was carried out professionally and within budget, except for agreed instances of unforeseen problems showing up. The workers were punctual and polite, which meant that there was a very good atmosphere throughout the period that the work was being carried out. Without any hesitation, I recommend P Marczak Building Ltd."

> "After agreeing a commencement date in writing, this contractor cancelled 3 working days before the start date. The job was to change the flooring to two rooms in a small flat, and I had prepared by emptying the rooms and removing the old floor. The cancellation left me with a flat that's hard to live in - two unfurnished rooms with no flooring and one room full of all my things. I had contacted a few contractors about installation of an engineered wooden floor and some other minor jobs. I got two responses. I've had bad experiences with contractors in the past so I asked for a contract - the other contractor provided me with their standard contract, Przemek said he wouldn't usually use one for a small job and said I was welcome to create one if I wanted, so I did. He seemed very reluctant to have a contract, which to me seemed a little odd - I sensed that the need for a contract was putting him off doing the work. I let him know my desired start date, and again he seemed reluctant to confirm. Eventually, he said he couldn't start on this date and gave me another date. We confirmed this date in writing. Then, three working days before the start, he said he could no longer do the job. Interestingly, despite being adamant there was no need for a contract, he used not having a signed contract as a reason it was ok to cancel at such short notice."

## Before you hire a builder
_What to check when choosing this kind of trade — general guidance, not a claim about this business:_
- Never pay a large deposit up front — agree a staged payment schedule tied to completed milestones, and hold a small retention until snagging is done.
- Get it in writing: an itemised quote with scope, materials, start and finish dates, and how any changes (variations) will be priced.
- Be wary of a cash-only price or pressure to start tomorrow — both are red flags for an unaccountable job.
- Ask to see a portfolio of completed work like yours, plus recent references you can contact.
- Check the credentials and registrations that matter for this work — and that they are current.
