What is Commercial Contracting?

A commercial contractor is a general contractor who specializes in constructing commercial buildings for business. A commercial contractor overseas the construction site and makes certain that everything is running like clockwork. A commercial contractor is in charge of project management, materials, vendors, equipment, contractors, and subcontractors (ATC doesn’t use subcontractors, but more on that later!) – we are responsible for everything from the beginning of your project to its completion.

What is Commercial Building Construction?

Commercial building construction involves the design, building, and renovating commercial structures such as office buildings, retail spaces, industrial buildings, and warehouses. Business owners, property managers, and developers hire commercial contractors to build or remodel their commercial buildings.

Common Types of Commercial Construction Projects

Commercial construction encompasses a wide array of building types. Some of the most common project types a commercial contractor works on include restaurants, schools, hotels, retail centers, factories, warehouses, and sports facilities.

Airtight Construction has worked on many different types of commercial building projects throughout the Bay Area and Northern California. From small scale ones like office remodels and building repair to large-scale projects like constructing a building from the ground up, we’re well-versed in all areas of commercial construction, giving us a unique perspective that allows us to meet your needs and bring your visions to life.

Can a General Contractor Do Commercial Work?

Yes! All commercial construction contractors are general contractors with a specialty in commercial structures. Some general contractors have the skills and knowledge to work on both commercial and residential structures, but most will specialize in one or the other.

Here at Airtight Construction, we do some residential construction work, but our main focus is on commercial construction, and we’re proud to be a premier commercial contractor in the Bay Area.

No Subcontractors Means Peace of Mind

It’s common for general contractors to hire subcontractors to complete certain aspects of a project. This is because some contractors lack the skills or experts necessary to handle every area of a construction project.

Here at ATC, however, we never hire subcontractors, which gives us full control over every part of your construction project. From time management all the way down to our quality of work, we have complete control, which gives you peace of mind that your project will be completed on time and to the highest quality and craftsmanship possible.
