Who We Are

A Family Run Business — Over 30 Years of Construction Experience

Wolsten was created out of frustration from friends and family who were forever being let down and overpromised and underdelivered by tradespeople and the construction sector as a whole.

We decided to set up a building company founded by three family members — Liam, Ryan and Paul — with the goal of delivering on every promise and providing excellence in construction. Liam and Ryan are brothers, with Paul their uncle.

With over 30 years of experience and a combined 60 years of on-site expertise, every project carries our family name — and that means everything to us. We serve homeowners and property investors across Bolton, Manchester, Liverpool, Preston, Warrington, Wigan and the wider North West.

Liam spent about 40 minutes on the phone with me offering free advise on work that was advised through a personal survey. He gave me a lot of clarity and put a lot of my worries at ease. He went through each concern and game me contacts of specialists in those areas. Amazing and so king to give me free advice!!

I worked with liam and the team on a HMO conversion in Preston.
We rewired the full house ensuring all emergency lighting and smoke detector systems were to regulations. We also installed Arc Fault Detection Devices to ensure additional protection for the electrical services.
It was a pleasure to work with them and everything went smoothly i would have no problem doing work for Liam and the team again.

Recently reached out to Liam and the team for help replacing a steel beam supporting a knock-through on the ground floor of our house, a project that was itself the first stage of fixing a non-compliant loft conversion carried out by a previous owner.

FarrellWolst were happy to discuss the project at length and provide excellent and much-needed advice even before we had asked them to carry out the works.

Communication was excellent throughout, as was their commitment to getting the job finished properly, even as we encountered unexpected problems.

First stage of this project looks great and has now been signed off by our local building control department. We look forward to having Liam and the team back at a later date to complete the loft conversion!

We had our garage converted from a storage area to an office / gym. It took 7 days, including fitting a new door and window. Everything went perfectly and whatever was promised was delivered.

Absolutely delighted. Liam and Paul converted my garage for me, into two rooms. One is a storage area and the second is a work area for my business. All completed in 4 working days (HARD WORK!) Couldn't recommend enough.

I had a Garage Converted in August. I had it converted to a storage room to an office with heating and electric. It's fully kitted out, to a really good standard. I would recommend.

We had artificial grass put in the back garden and are so pleased with the result. Liam was great all the way through the process and delivered a brilliant result, would highly recommend.

Recently had our back garden transferred from a mud patch into an amazing space to relax in and the kids to play, the artificial turf recommended was perfect and expertly fitted, after a few recommendations from Liam he knocked up a small flower area with some sleepers to finish the garden off.

Would highly recommend fantastic work and a food price to.

Would recommend. Very happy with the loft; the guys were always on time, polite and never left mess. The double wonder staircase was a challenge with the space and access but Paul fit it with incredible skill!
Thanks
