There are several factors that go into calculating how long your remodel project should take. The design phase of your project is often the fastest, though some homeowners can take weeks to months to make the final decisions on the design. After the design is finished, all of the materials will need to be ordered and delivered. This can take anywhere from 8 to 12 weeks to complete if you are ordering all new cabinets as well. Once everything is on-site the renovation can truly begin. From start to finish this process will usually take around eight weeks. This time can vary depending on the complexity of the job.
