Extensions- 30 May 2022
Mark Austin was engaged to remove and replace an old parkhome porch. Although not the cheapest quote, he did provide an honest and realistic appraisal of the job and accounted for customer preferences within his design. An amiable and industrious character, Mark always turned up on time at the times agreed and worked with busy intent while on site and always tidied up after the days work. What he left us with is a solid, sound structure that is clean and bright and easy to maintain. I would not hesitate to recommend Mark Austin Glazing and Building in the future.

We’re really happy with the work Leon carried out on our house. He removed an old sliding door and the adjoining wall, rebuilt the new section, plastered it and fitted our new door to a really high standard. Everything was done with care and great attention to detail. We were so pleased that we’ve already booked him in for more work later this year. Would highly recommend!! 😊
