Hiring a general contractor is a good idea for many remodeling projects. Home renovation contractors have a broad range of skills to manage, coordinate and complete a project. They should help make sure your project comes in on time and within your budget as they hire and supervise all the necessary subcontractors, including electricians and plumbers. They also handle procuring all the materials required for your job. Some homeowners look to save money by acting as their own contractor, but an experienced home renovation contractor is worth the cost. They should know local building codes, be able to pull all necessary permits, and work with inspectors to make sure the construction meets local codes. Also, because they get professional discounts, they can typically buy materials at a better price than you can; better prices on materials and labor save you money, and make up for at least a percentage of the cost of the contractor.
How often you should clean your air ducts depends on your situation. If you or someone in the home has asthma or is acutely allergic to certain airborne materials or pollen, regular duct cleaning may be helpful. The Environmental Protection Agency doesn’t have an official position on the necessity of air duct cleaning unless the ducts have been contaminated by rodents, insects or mold, or you are aware of particles blowing out through the vents. The EPA recommends you have your air ducts cleaned on an as-needed basis. The National Air Duct Cleaners Association (NADCA) suggests having air ducts cleaned every three to five years.
Be cautious with companies that offer “whole house air duct cleaning,” urges the NADCA. The company may be using unscrupulous tactics to upsell you once they get started. Before any work begins, always clarify in writing what the job entails and what the cost will be. To protect yourself against fraud, read customer reviews and verify that your HVAC cleaning service has applicable licenses and certifications.
When starting a home remodel or new construction project, you will probably hire a general contractor. A general contractor is a professional who is qualified to take a set of building plans and construct them as outlined. The general contractor may help perform the day-to-day building, or they may just hire workers and oversee all the work activities. In either case, the job of the general contractor is to see that your project gets built.
When you have a building project, ask for bids from various contractors. The bids tell you how much each will charge and what their scope of work will be. Once you have selected a bid, you sign a contract with that general contractor outlining the specifics of the project and the milestones during the project when they will receive payment installments. Once the contract is official, the general contractor will bring in their crew to begin construction. The contractor will manage the workers and subcontractors (anyone who doesn’t work directly for their company but that they need to outsource, like a marble installation pro), order all the materials, obtain work permits, and confirm that all the workers and subcontractors are completing their projects as planned. They typically handle all the payments to the workers and subcontractors, and send you invoice. For all these reasons, it’s also especially important to follow a few smart hiring practices when it comes to finding a general contractor. If you are organized and competent to oversee construction projects, and are able to make sure everything is being built properly and meeting code, it’s possible you can be your own general contractor.
Air duct cleaning is done by heating, ventilation and air conditioning (HVAC) professionals. The pros use industrial-strength, truck-mounted vacuums and powerful brushes and hoses to clean inside the metal ducts that make up your forced air heating and cooling system. The Environmental Protection Agency recommends duct cleaning if there is “substantial visible mold growth inside hard surface ducts, ducts that are infested with vermin such as rodents or insects, or ducts that are clogged with excessive amounts of dust and debris and/or particles are actually released into the home from your supply registers.”
You should also have air ducts cleaned after recent water contamination or water damage to prevent mold; after renovations or remodeling to ensure debris and dust didn’t settle in the vents and ducts; if you are having problems with allergies or asthma; or when you are moving into a newly purchased home, especially if the previous owners smoked or had pets. The National Air Duct Cleaners Association (NADCA) recommends getting your air ducts cleaned every three to five years, or every two to three years in regions where homeowners use their air conditioning and heater for many months of the year, while the EPA suggests homeowners have duct cleaning done as needed.
If you’re doing a home remodel, building a new home or embarking on a commercial building project, you’ll hire a general contractor. A general contractor is a professional who is qualified to oversee and execute construction projects. Each construction project is unique; even two duplicate homes built on lots next door to each other could have different construction costs due to factors like different excavation costs when building the foundation. Since each project is unique, many general contractors make bids on potential construction projects. These bids can then break down to a per square foot cost that encompasses the labor of all the workers needed for the job, materials, the scope of work, and any equipment needed. Materials and finishes make a major difference in your cost per square foot. For example, choosing standard kitchen tiles at $3 per square foot will result in a lower total project cost than imported marble tiles that cost $63 per square foot. Where you live will also affect how much general contractors charge, as labor and the cost to do business can cost less in many regions than in high-cost areas like New York or San Francisco. Here are some examples of average costs general contractors typically charge in various regions:
- Home addition in San Francisco: $250-$270 per square foot.
- New home construction in Knoxville, Tennessee: $100-$200 per square foot.
- Kitchen remodel in Tennessee: $40-$80 per square foot, depending on finishes.
- Bathroom remodel in Vancouver, Washington: $110-$170 per square foot.

If you’re concerned about dust, allergens or mold, it may be time to have your air ducts cleaned. The national average cost for air duct cleaning ranges from $190 to $250. Air duct cleaning costs will vary based on a number of factors such as your location in the country, the age and condition of your air ducts, the number of linear feet to be cleaned, and any repairs your ducts may need. HVAC cleaning companies should clearly outline what is included in their services and at what rate, so always make sure you understand and have a written agreement before work begins. Here are some examples of average air duct cleaning costs:
- Tiered pricing for different levels of service:
- Standard cleaning: $100, which may include truck-mounted industrial vacuums, high-pressure air wands and air snakes to clean all supply and return vents, branch lines, and main trunk lines.
- Advanced cleaning: $200, which may include standard cleaning services, plus rotobrush or viper clean sweep in the main trunk lines.
- Ultimate cleaning: $400, which may include advanced cleaning, plus insertion of a viper microline into all vents to force debris down the branch lines and into the main trunk lines, to be handled by the viper clean sweep. Typically, all ductwork surface is contacted, before-and-after photos are provided, and the furnace is cleaned.
- A flat rate for unlimited vents: $289.
- Additional fees for larger houses: $20 for each additional 500 square feet over 2,500.
A commercial contractor provides similar services as a residential general contractor but specializes in working with large-scale projects for businesses, schools, nonprofits, governments and development firms. When researching commercial general contractors, review their portfolio of work and confirm they have ample experience working in the area you need. For example, if you are building a small strip mall, ask if the contractors have experience successfully incorporating all the needed elements such as a parking lot, meeting ADA requirements, accessing the proper permits, and completing work on time.
Once you’ve identified several qualified candidates, request bids for your project and then compare the scope of work with your needs and budget. Your commercial general contractor should oversee design, permitting, construction, materials purchase, and adherence to building code and zoning regulations, as well as sticking to an agreed-upon budget and schedule. It’s important to establish clear communication with your future commercial general contractor, as this will mean a smoother process for everyone. For all these reasons, it’s also especially important to follow a few smart hiring practices when it comes to finding a general contractor.
The amount of time air duct cleaning takes can depend on how extensive your duct system is, how old your air ducts are, and whether they have ever been cleaned. On average, expect a standard size home (between 2,000 and 3,000 square feet) to take 2-5 hours for one to two technicians to clean. Here are the proper protocol and equipment you should expect from a professional duct cleaning service, as recommended by the Environmental Protection Agency:
- All doors and access ports opened to ensure the entire duct system is inspected and cleaned.
- Thorough system inspection prior to cleaning to identify possible asbestos-containing materials. If asbestos is present, specially trained and equipped contractors must do the removal.
- Use of approved vacuum equipment that exhausts particles outside of your house. If the vacuum exhausts inside your home, it must be HEPA equipment.
- Furnishings and carpet covered and protected.
- Soft-bristled brushes only on fiberglass duct board and sheet metal ducts internally lined with fiberglass.
- Ductwork properly protected.
- Adherence to guidelines and practices set down by the National Air Duct Cleaners Association.
The national average dryer vent cleaning costs range from $190 to $260. Dryer vent or duct cleaning costs can vary based on where you live in the country and what ductwork repairs may be required. Duct cleaning pros will use a brush cleaning method, a forced air vacuum, or a combination of the two to remove lint and other debris that can collect in your dryer duct, lint trap housing and vent. If left unchecked, this buildup of highly flammable debris can catch fire and lead to a home fire, says the U.S. Consumer Product Safety Commission. In addition to home safety, a great reason for regular cleaning is the money you’ll likely save on energy bills and improved indoor air quality. Pros may offer a lower rate on their dryer duct cleaning costs when you also hire them to clean your entire HVAC duct system. To ensure you’re working with a pro who will keep your home as safe as possible, read their reviews and check whether they have been certified by a reputable organization such as the National Air Duct Cleaners Association (NADCA) or the Chimney Safety Institute of America (CSIA). Many duct cleaning pros will also show you before-and-after photos as proof of the cleaning.
A few home remodeling projects can be done by an ambitious DIY-minded homeowner or local handyman, but many are best completed by a professional home renovation contractor. You should hire a contractor when you’re planning a large project that takes time, machinery or large tools, and several workers; a kitchen remodel, new bathroom or home addition will be most successful with a licensed, expert contractor at the helm. It’s particularly important to have a professional contractor on board for construction, electrical, plumbing and HVAC projects that require inspections to meet local building codes. Of course, you can hire a contractor for smaller projects, too, if you prefer to let an expert handle things like addition or removal of a wall, small framing projects, or anything that requires a permit.
You should hire a contractor when you’re ready to start a remodeling project and you have plans, a budget and a timeline for the work in hand, but before any remodeling work begins.
