We needed a complete chimney rebuild. Having used Wilkens previously for a couple of smaller jobs we called them for an estimate. They climbed up to inspect the chimney and provided a detailed estimate, unlike the other two companies who just eyeballed it from ground level and grossly overestimated. We were given an approximate two week window for commencement of the work, weather-dependent, and true to their word called the day before to confirm. They arrived promptly at 8am, worked steadlily all day and came back the next morning for a couple of hours to finish and clean up. We couldn't be more pleased with the work and the service.
