What Is a General Contractor?


General, or construction contractors, are often known as project managers. They oversee the entire remodeling or new home construction project and facilitate all day-to-day tasks that move it toward completion. A general building contractor will work with your architect to review plan as you build a house and ensure everything is in place before work is started, as well as arrange for permits and necessary inspections. While good local home improvement contractors will have the skills to handle certain tasks onsite, such as carpentry, he or she is also responsible for hiring subcontractors for the majority of jobs, such as electrical work, painting or plumbing. In addition, the general contractor should be on-site regularly to inspect the progress and resolve issues. Here are some related professionals and vendors to complement the work of general contractors: Architects & Building Designers, Interior Designers & Decorators, Landscape Architects & Landscape Designers, Kitchen & Bath Designers, Specialty Contractors.

Home remodeling contractors are a must for successful completion of a renovation. Because of this, it's essential that you do your homework before deciding on the right London, ON general contractor as you remodel or build a house. Inspect bids carefully. Was it ready when the contractor promised it? Was the bid for building a home unusually high or low? Each of these things can be very telling: A late bid may reflect timing standards, and an off-the-mark bid could be code for a pricey premium or a deliberate underbid to score the remodeling job. You should call references, carefully read reviews and visit London, ON completed projects to see if they’re what you expect for your job. Once you do secure your local contractors, read the contract very carefully to be sure everyone is on the same page.

Questions to ask prospective general contractors:
