Owner John Scalmanini looks over drafts for a window installation project.

Anderson Window & Door Installation provides a wide selection of windows and doors for residential customers in Santa Clara and San Mateo Counties. The company can also install flashing and match stucco texture, and it backs every window and door installation with a lifetime warranty.

Owner John Scalmanini founded Anderson Window & Door Installation in 2000. A licensed general contractor with 30-plus years of industry experience, Mr. Scalmanini estimates he has managed more than 85,000 window installations throughout his service area.

Anderson Window & Door Installation is a Certified A-Plus Dealer for Milgard Windows and Patio Doors, a Circle of Excellence "Platinum" Dealer for Andersen Windows and Patio Doors, and a Certified Simpson Door Dealer. Mr. Scalmanini supervises every job and says he takes time to make customers aware of all their options. “If they’re able to make informed decisions, each customer will receive the finished project as they imagined it.” To see examples of its products and their applications, potential customers can visit the company’s San Jose showroom.

“We’re committed to providing complete customer satisfaction by delivering quality products at competitive prices. Our professional installers maintain the highest standards of ethics, service and workmanship; they’re a tight-knit team and they take pride in a job well done.”

When replacing windows and doors, choose a company that’s a certified dealer for the products it installs. “It’s important for the firm to have relationships with the manufacturers of its products,” says John Scalmanini, owner of Anderson Window & Door Installation in San Jose. “To become a certified dealer, you can’t be someone who only installs a few windows per month. You have to be experienced and prove you know how to do service work. Also, once certified, companies receive preferred pricing and training directly from the manufacturer.”

Homeowners should also be wary of low bids. As a rule, contractors bidding on the same job shouldn’t have radically different prices. If one bid is considerably lower, it’s either because the contractor has made a mistake and is bidding a smaller scope, or they’re using substandard materials or labor. “When you take the low bid, you’ll get a poor installation most of the time,” says Mr. Scalmanini. “You don’t get something for nothing in this industry.”

When it comes to maintaining your windows and doors, not much work is required. Mr. Scalmanini advises to take basic maintenance steps, such as keeping the paint in good shape. “You should also inspect the seals and caulking every few years to make sure they aren’t cracking or splitting. If they are, call the installer and have them fix the problem. But if it’s a good installation, you shouldn’t see those problems. You should see nice seals for years and years.”

Anderson Window & Door Installation has been providing new and replacement windows and doors for Santa Clara and San Mateo County homeowners since 2000. The company is a certified dealer for many top window manufacturers, including Andersen, Milgard, Marvin, Simpson and JELD-WEN. As a Class B general contractor, it also handles construction work associated with window and door installations, from framing and stucco application to sheet rock and trim work.

Owner John Scalmanini has more than 25 years of experience in the contracting industry. Mr. Scalmanini says he's proud of Anderson Window & Door Installation's ability to handle numerous aspects of its clients' window and door projects. "We don't subcontract any of our installation work–it's all done by our highly-trained installers. A lot of companies pay their workers per window. That encourages them to work more quickly and cut corners so they can install more windows and earn more money. My employees are paid by the hour, so they take the time to do the job right."

Whenever Anderson Window & Door Installation replaces a window or door, it performs a full replacement instead of simply inserting a product into an existing frame. "That causes problems," says Mr. Scalmanini. "You can't get a good seal on a window unless you replace the frame, and door panels will warp if placed in an old frame."

The company is also a certified dealer for all the products it sells and installs. "We buy directly from the manufacturers, which allows us to be very price competitive," says Mr. Scalmanini. Because it's a certified dealer, manufacturers entrust and pay Anderson Window & Door Installation to handle any warranty service work that's required on their products.

Mr. Scalmanini's firm is part of Andersen Windows and Doors' "Circle of Excellence," the highest certification the manufacturer offers. As a result, the company receives preferred pricing on Andersen windows, and its installers are factory-trained to service various products. "It took us five years and a lot of window installations to achieve this certification," says Mr. Scalmanini. "Now, we can pass the pricing and benefits of that training on to our customers."

The quality of their products is really good. They did my front entry door. They have a large selection to choose from and they are good quality materials. They were professional. They came out and did the estimate and nothing changed with it. Karen at the office, was really on top of it, because I had to have my door special ordered, but she kept me informed throughout the whole process. They also cleaned up after themselves really well.

My door is amazing. They were able to install this unique door when several other companies said they couldn't do it. My experience was so great.

They have a very good price on the windows I chose. The owner is local and very dependable, as far as time is concerned. I liked the punctuality and ease of communication with Karen in the office. The quality of the men who came out was amazing. They were very polite, very neat, clean, and professional. My boyfriend is a building contractor, and he said they were fabulous.

I had several bids, but I liked his bid the best. I really like that he's a local business. He's on his own, and he's making it work. He spelled out what he was going to do and was there all the time.

It was good. I dealt directly with John, the owner, and it was really good. I dealt with two previous companies and I was not satisfied with them. Anderson knows their stuff and I do too as I was in charge of replacing at least 10,000 windows in the area and I replaced all the windows in my house by myself.

They were upfront and they knew what I wanted. They were prompt about everything and they were easy to get to.

I'm a landlord and I have given John 30 to 40% of my business, as my father did before me. John and the company have always been very efficient, his secretary always calls the day before an appointment and they are just dialed in to whatever I need. The workers are bilingual and do an absolutely great job.

They were very good in consulting, by not pushing products on us. They gave us plenty of time and then when we made the selection, they got the materials, and scheduled the installation. They were on time, did a great job on the installation, and cleaned up. It was an outstanding client satisfaction case.

They were very professional, arrived on time, set up tarps, and then broke into teams. One team started working on removing the windows and once they were far enough along, the second team came in to do the installation. It was very efficient and the job was first rate. There were no surprises. John was great and his team was outstanding.

Well, we were impressed with the quality of the product and the advice we got going into it. Also, we were amazed by the quality of the stucco work that they did. It wasn't their main job, but you can't tell what was torn out and what was there before. We have used them before and were impressed.

I guess I'm saying they fit the product into our existing house. I liked their attention to detail that was ancillary to their main product.

We've used them before. I felt it was very personal. We had a question, and they responded immediately, very customer friendly. Their shop had lots of things we could see, so we could look at the handles and locks, and make decisions by looking at actual products. It's a small shop, but they were very responsive.
