We love speaking to our customers! Please call us direct 516-876-1999 or email our owner at [email protected]. Brian's dad, Bill Bonell began All Weather Guard in 1971 as a one man operation, doing all roofing projects by himself. After 47 years of great success, his son Brian, who graduated from Hofstra University with a Business Degree, has come on board and has taken over and plans to continue in the tradition of his father for years to come. The Bonell family has replaced tens of thousands of roofs in the Long Island area while turning houses into dream homes! We believe our success is due to our quality craftsmanship and excellent communication with our clients, making a winning combination. All Weather Guard listens to your goals and makes them happen. Put your trust in us and we guarantee you won’t find another remodeler that cares about the end result as much as our professional crew.

"All Weather know what they're doing and they do it right. Bill and his son Brian are true professionals and gentlemen who have been in business for over 50 years. We had new roofs and gutters installed on 2 houses in Port Washington. The crew did an excellent job on both and one was a very architecturally challenging 100 year old house. The crew and the owners exceeded my expectations and I would highly recommend them."

Protecting homes and businesses since 1950, Guardian Protection is one of the nation's largest and most highly regarded security companies. We provide smart technology, 24/7 professional monitoring, and peace of mind to hundreds of thousands of customers. Our products are installed by experts, monitored by real people, and truly make a difference. We do what we do because of one simple truth: life is better when it's safe.

"We hired Guardian to install our security system at our Washington, DC, business. The service and quality of the work was horrible. We had cameras and an alarm system installed; it was a relatively large system. They outsource most of the work to various vendors. They could not manage their vendors; what was supposed to take a week took two months. The sales rep did not return calls, and you could never get anyone in management on the phone. Random people would show up at unannounced times. The few things that an actual Guardian employee did were they made a huge mess of our newly remodeled office and were rude to our staff. We have offices in five markets across the US and have high security at each; we have never had such a poor experience."

"Ray was everything. If you have a critter removal need, you've found your contact. He came immediately the day we called him and evaluated the situation (raccoons on our property) in a Raccoon Dundee style, which made us laugh! He has decades of experience in wildlife removal and it shows. He was efficient and told us exactly where and how many raccoons were on our roof and how long they'd been there. He gave us two options for removal and explained the benefits and explanation for using each one. One route involved a lower fee and focused on tactically chasing the animals away rather than trapping. We chose this option and so far the animals have not returned. Ray called us within a week to check in on the situation. We learned so much from this experience about raccoon behavior - it was an education combined with a removal! Call Ray, he's THE BEST!"

"Jim Flanagan did a great job on our project. We really enjoyed working with him on our kitchen upgrade, painting, floor refinishing and other touch ups we needed done to the family home we were selling. Not living locally was a challenge but Jim made this workable with his prompt communication, advising us on certain supplies and materials he noticed on sale, meeting us when we were in town and recommending other great people to work with. He was fair, honest and flexible. He did great work himself and made sure others he hired did the same. He helped us stay on budget and finish in our hoped for time frame. The sale of the property went well and buyers liked the improvements Jim made, especially the kitchen upgrades of the countertop, appliances, tile backsplash and flooring.

Insulation questions, answered by experts

Yes, you should insulate your PEX pipes if you’re wondering how to keep water pipes from freezing. Pipes in uninsulated rooms or outside the house should always be insulated. If you’re looking to save money, you may not always need to install insulation on PEX pipes that are running through interior walls with insulation.

The easiest way to cover your HVAC ducts during construction is to use painter’s tape to affix plastic sheets over your vents and air returns in the area of your home where construction will take place. Keep in mind that closing off a portion of your system can put strain on your blower motor and air handler, so either shut the zone off or shut your system off while construction is underway. If you shut the zone, you can also hang plastic sheets over doorways to separate the construction area and keep dust contained.

The thickness of floor insulation will depend on the R-value you plan to achieve. R-value varies on the type of material as well as its thickness and density. Insulation materials with low R-values can be layered to match the value of denser materials. As long as your floor insulation is packed tightly, seals the area from drafts, and doesn’t prevent ventilation, it can be as thick (or thin) as you need.

The most affordable way to insulate behind unfinished walls is to install fiberglass batts or rolls. These total around $0.75 per linear foot, with the width matching the gaps between standard studs perfectly. However, it’s important to consider the R-value of your insulation and the climate in your area, as fiberglass insulation isn’t the best in terms of preventing heat transfer. Plus, the most affordable option may cost more on electricity bills over time. The most affordable way to insulate behind finished walls is to leave them up and use blown-in insulation to avoid drywall replacement.

These two types of foams are similar chemically, but they are applied in a much different way and each has its own pros and cons. Spray foam can only be used if the area where you will be installing the installation is wide open and easy to access. Injection foam should be used where it's cost-prohibitive to remove the walls that are placed over the insulation. Spray foam is a much less expensive process and requires less expertise.
