Why SigmaSigma Exteriors is the premier roofing, gutters, siding, and window
replacement contractor in the Wisconsin Area. We are a locally owned and
operated company that has received national recognition for our unique
customer-first processes and procedures
We make the process of home-improvement easy and worry-free. Our
company name and logo says it all. ‘Sigma’ in Sigma Exteriors is
derived from the management philosophy called ‘6-Sigma’. Basically,
6-Sigma is a process of constant, never-ending improvement leading to
100% Client Satisfaction.
You’re probably not aware that a recent national survey found that
Home-Improvement Contractors are the #1 most-complained about business
in the United States!
Because of this fact, and Sigma Exteriors’ dedication to achieving
100% Client Satisfaction, we have developed the most customer-friendly
home-improvement experience available. This is why WTMJ News Radio chose
us to be their My Home Improvement Program’s Window Replacement,
Siding, and Roofing Expert. Additionally, we are also the featured
experts on Milwaukee’s Builders Showcase.
Out of the hundreds of contractors in Wisconsin, we are the only ones
that:
- Take a consultative approach to providing you with solutions to
your home-improvement needs. We respect your ability to make
the right choices for your home without the need for high-pressure
sales tactics. And since we represent several major home-improvement
manufacturers, we’re sure to have what you’re looking for.
- Ensure quality workmanship, by providing installers that are
highly trained and certified in the latest installation techniques.
Shoddy workmanship is not tolerated here at Sigma Exteriors.
- Complete most jobs in 1 day, minimizing the interruption to your
daily routines. This is made possible by our certified and highly
trained installers.
- Provide you with a clear and detailed estimate. We know that
improper initial inspections along with vague, handwritten estimates
leave you vulnerable to hidden charges. At Sigma Exteriors we
conduct a thorough inspection of your home before providing you with
a laser-printed estimate, which details out the problem found, the
work that needs to be done, the materials being used, the related
costs, and the projected completion date.
But don’t take our word for it. Compare for yourself by learning more
about the Code of Ethics & Competency
Consumer Protection Program.
This program consists of many vital points that any legitimate and
worthy contractor should be able to supply you without hesitation, in
order to validate and prove that they are capable of handling the job.
The idea behind this Code of Ethics program, the video, brochure, and
Compliance Checklist is to put the burden of proof regarding
character and competence on the contractor’s shoulders where it belongs,
and not on the unsuspecting shoulders of you, the consumer.
The Code of Ethics “Protection Points” are categorized into 4 main
areas:
- Reputation of the contractor
- Stability of the contractor
- Quality of the workmanship being promised
- Professionalism and service
The Code of Ethics program will make it simple and easy for you to
immediately distinguish good contractors from bad ones by providing you
a “Contractors
Compliance Checklist.” Make copies of this list and hand one to each
of the contractors you are considering. Ask them to return the
compliance certified documentation to you at the exact same time they
give you their bid. Please, don’t ever accept any bid without the
accompanying documentation from the compliance checklist. Again, this
puts the burden of proof on the contractor and not on you.
