"Ryan was perfectly on-time and was a plumbing scholar and a gentleman. We had a simple drain replacement under a new sink. Going to Western saved me at least another day of trying to figure out proper parts and doing the install myself, and it also saved my wife's ears from hearing my salty language."

"From beginning to end, The Right Choice Heating and Air Conditioning Co. provided superior quality customer service and onsite work. From scheduling, to multiple follow-ups and reminders, re-confirming exact appointment time, and the post-inspection follow-up, they have truly impressed us. More importantly, Michael Taib, the technician who performed the work at our home, was indeed a true gentleman and professional. He was extremely knowledgeable and patient. I am familiar with the type of HVAC related work requirements, the lingo, and technician data. I quizzed him several times and he constantly responded with 100% honest and factual answers. He tirelessly worked on both of our HVAC units and performed the necessary services and repair. He was polite, courteous and clean. His most impressive talent was ensuring my wife's absolute confidence in his work after she grilled him with so many questions! We will continue to refer True Choice to all our friend and family! Call them; you will not be disappointed."

"Wesley was extremely responsive. He made all efforts allowing us to continue doing our business at home while he was assessing the problem, assembling his crews, and obtaining a City permit. We were well informed of the progress. His crew did an excellent and clean job, working long hours getting the job done. Including excavated to a depth of 10 feet, patched up our concrete driveway and patched up the AC roadway nicely. Wesley even found time to replace our kitchen faucet and under drain without extra charge. Don’t believe he would be the cheapest initial estimate you would get. We would definitely ask him for all future plumbing needs."

Subcontractors questions, answered by experts

No, builders and general contractors don’t expect tips. In fact, some companies may prohibit their employees from accepting client tips. If you want to show gratitude for a job well done, consider writing a review of your builder or contractor or agreeing to be a reference for potential new customers.

A construction lien results from unpaid services. For instance, if a homeowner hires a contractor to do a large renovation on their home and then fails to pay for the services and materials, the contractor can take out a lien on the property. This lien is a legal claim against the property for the amount of money owed. If the homeowner does not pay their debt, the lien may stay on the title until the homeowner tries to sell and cannot do so until the title is cleared.

Depending on your structure, you may not need planning permission. Major excavation, anything that changes the external appearance of your home, or any construction that will affect your neighbors will need planning permission. However, no planning permission is required if you’re just converting an existing space into a root cellar.

A contract should outline the scope of work, timelines, costs, payment schedule, and materials used for clarity and protection.

It pays to hire a project manager or general contractor when you have a large-scale project that will take over a week to complete, especially when it involves structural changes and multiple subcontractors. This includes hiring a general contractor to build a house, add an extension, or manage other projects that need a building permit.
