"Joe and his team of electricians led by Paul were amazing to work with! Very professional, on-time, and fair pricing estimates for electrical work I needed in my condo, including moving the position of a ceiling light and setting up two new sconces, both of which required patching up the drywall afterwards and they made it look seamless. Joe really values quality work and made sure to check in throughout the job and afterwards to make sure I was satisfied, answering any questions I had. They offer a ton of handyman services and I will be booking them for future tv mounting needs as well."

Security Doors questions, answered by experts

There are certainly perks to hiring a general contractor, but we recommend a closet professional. The reason is that their pricing may make more sense for your project. General contractors tend to search out bigger projects, and because of this, will attach a premium to smaller amounts of work. A closet pro may also have access to a wider range of materials than general contractors (and may be able to negotiate better discounts). 

A deadbolt lock is typically considered more secure than a regular lock based on its internal construction. Each deadbolt type has varying levels of security, ranging from withstanding a small amount of force to those that can take on multiple strikes and greater force. Regular locks provide little to no security and are typically used more for easy entry and simple installation.

If your home cannot accommodate a traditional garage door, there are plenty of other options to choose from. Consider installing a door made of glass, fiberglass, sheet metal, or faux wood. You can also choose a unique style like a folding, tilt-up, sliding, or carriage door. Consult a local garage door installer to discuss the options available for your garage shape and size.

Wood is by no means the only type of front door material on the market. You can also choose from several other options, including:

  • Aluminum: Low-maintenance and affordable, but lacks insulation 

  • Fiberglass: Offers excellent insulation and durability for a decent price 

  • Glass: Offers beauty but less security or insulation, and a higher price tag 

  • Steel: One of the most economical options if you’re looking for affordability, low maintenance, high security levels, and a door that will last

  • Wrought iron: Attractive and secure, but costly and heavy 

The average fiberglass door that you purchase from your local door company or home improvement store will last around 20 to 40 years, so fiberglass doors are considered durable compared to other door materials. When properly maintained, it's not unheard of for a fiberglass door to last up to 80 years.
