Guttering- 9 May 2018
Absolutely fantastic job. Worked like a trooper in all weathers. Nothing was too much Trouble and the work has been finished to a very high standard. Cleared up after himself each evening and worked through into the evenings often. Even the rain did not put him off and carried on working soaked through. If you are looking for a true expert for finlock guttering removal or replacement. Jason Shaw is your man. We had all concrete guttering around the bungalow removed and also removed from inside the conservatory. He made sure all openings were securely covered , taped up so we had no dust in rest of the house. We can highly recommend him .

Landscaping- 29 Aug 2024
Will came and looked at the job, we talked, some banter, my wife and I felt comfortable with him and bearing in mind Sam my wife would be in and around whilst I at work that was very important…a good start. We had the quote, happy with the cost and the plans after my very poor landscaping drawing and a date was penned in. 8am Will and able teammate Kev arrived to start the excavating to take out the grass and make good ahead of building brick circles to be surrounded with blue slate clippings and artificial grass in the centre of the circles plus extending the patio. 10 days or so later including working the bank holiday we have a lovely garden to be proud of. Both Will, Kev and digger driver John were polite, courteous and respectful of the property and in our opinion have done a cracking job… Needs arise in the future, only one phone call to be made in my opinion…top job guys

Will my home extension meet all building regulations and planning requirements?

Your St Columb extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in St Columb?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the St Columb extension builder’s ability to deliver a result that meets your expectations.
