"Nick provided a top-to-bottom, end-to-end renovation/upgrade to a two bedroom apartment for sale including the full bathroom from floors to walls to shower and sink faucets, vanities, mirror and medicine cabinet demo and installation, repaired/filled holes and painted - basically everything other than the tub replacement so that it was a brand new, spotless room. He continued this effort and workmanship in every room and demoed and installed all new pergo flooring for the open floor plan kitchen and living room and bedrooms, landings as well as new stairs replacing dated laminate and carpeting. The kitchen cabinets, countertops, faucet, etc. were completely updated and made the most of the space while being designed in way to fit an over the stove microwave in the future. Future designs were factored into the cabinet layout/installation. He repaired/filled large holes in walls, ceilings, doors left during a move-out and painted the entire apartment to make it fresh and updated where you couldn’t notice the holes anymore. Incorporated all the finishing touches that a realtor identified to complete the renovation. Constantly receive compliments on the impressive finished product of our newly renovated apartment that is ready to move in."

Window Door Contractors questions, answered by experts

Adding a doggie door can allow a burglar access to knobs and locks on your door. If your pet door doesn’t come with an alarm, you can add a weight sensor alarm that will trip if anything heavier than your pet enters through it. Adding a motion sensor light to the room your pet door is in can also help deter burglars.

French doors can add value to your home by increasing curb appeal. Having French doors that lead to a patio or porch will add an eye-catching feature to your home that may raise its resale value. If properly installed, French doors can last as long as 30 years, so French doors often have a good return on investment.

A security door costs an average of $1,400, but costs can range from $600 for a simple screen or steel door to more than $4,600 for a wrought-iron security door. You can also buy specialized locks separately for $200 to $600. If you decide to hire a pro to install your new security door, you’ll spend around $275 to $425 on labor costs.

Steel doors last 30 to 100 years, making them among the most durable and longest-lasting doors on the market. However, they will likely get dented and scratched during that time, and if the paint peels, they can show signs of rusting.

French doors can either open inward or outward, but because hinges are the mechanism for opening and closing, a single set of French doors will not be able to do both. Most French doors only open outward onto a patio, deck, or porch, while some only open inward if the outdoor space is limited and can’t accommodate the open doors.
