Buying A Roof, Replacing Your Windows, Or Changing Your Siding Is A Hassle.

Ten companies. Ten quotes. Ten salesmen. Each one sells the product he is paid to push. None of them go in your attic or look below the surface.

So you guess. You pick a name. And before long you learn you fixed the wrong thing.

That Is Why So Many Homeowners Pay Twice To Solve One Problem:

Most roofs are replaced before they need to be

That draft is rarely the window. The window guy sells windows anyway.

Fix the wrong problem and you pay again to fix the real one.

You Should Be Guided, Not Sold.

You should not need a construction degree to avoid getting ripped off.

Flashing, ventilation, building science. That is our job. Living in a home you never think about is yours.

The Guardian Difference

Three Reasons This Feels Nothing Like Calling A Contractor

We diagnose. They pitch.

A Home Advisor finds the real problem before anyone says a price. No quota. No commission.

We carry every brand. They carry one.

No exclusivity deals. We recommend what you need, not what pays us most.

We insure the work. They "warranty" it.

Our workmanship is third-party insured. If we ever disappeared, you would still be covered.

A one-pitch contractor cannot copy this without rebuilding their whole business.

The expert's expert. 30,000+ homes in 30 years.

We trained Wisconsin's state home inspectors.

We advise Fortune 500 companies on building science.

We are certified with every major brand and owned by none.

Andy came out to assess the workmanship on an in-progress roofing and siding job that was being done on our house and garage by another company. Andy was very forthcoming and patient while listening to our concerns, and he pointed out every issue he found and explained why they were problems and what should have been done to keep with industry standards. He took his time to inspect the work that had been done and also took photos of all issues he found. He was able to give us advice on what we needed to do to protect ourselves and advised that we read through laws and procedures relevant to our project and issues we are facing (he provided information sheets with resources). I feel Andy is very knowledgeable, honest, and takes his job seriously, and I would be happy to work with him in the future.
My account rep was great to work with. He was clearly very knowledgeable and took the time to explain everything and answer all my questions.
I'm very happy and satisfied with my new roof. My old roof was in really bad shape. Andy Wilde was very professional and extremely helpful. He answered all my questions and addressed my apprehension. I explained to him that I had a maximum budget that could not exceed. He worked with me until we could get the cost to where I could manage it. He was great and I was very pleased. The construction crew were outstanding, they were on time, they protected my flowerbeds, yard and driveway. Once done, they cleaned up everything. Hector, was the project manager and he was on site several times to make sure the project was processing as it should and to answer any questions I had as the crew did the installation. All in all, they did a great job and I'm very pleased. I highly recommend them. Job well done.P!
We had a wonderful experience working with Big Fish. After getting several bids from contractors, we decided to go with Big Fish for new windows for our home. Communication throughout the experience was excellent. Paul did a great job explaining the timing and steps involved. The crew at our home were always professional and friendly. We would highly recommend Big Fish for any of your home or window projects.- The Donovan Family
Andy did a great job providing me with a quote for the exterior repairs at my house. He was very friendly and the complete opposite of the pushy salesman. I would recommend working with Andy based on this experience.

FAQ

Questions homeowners ask us

Will you try to sell me something I don't need?

No. We diagnose first. Sometimes the answer is a small repair. Sometimes it is nothing at all. We tell you either way.

Sometimes our price is higher. The difference is the diagnosis and an insured install, so you do not pay twice.

Our workmanship is third-party insured. Even if we vanished, you are covered. Nobody else here does that.

Welcome to the "No Sales Guy" Zone.

Most companies send a salesperson. We send a Home Advisor. You get a diagnosis and a clear next step. Not a pitch.

Buy it right the First Time.

Most homeowners overpay because no one diagnosed the real problem first. Let’s fix that.
