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."

We are a small local owner operated business, all of the work performed is done by myself with employees no sub contractors are used for carpentry work. My work mostly consists of custom kitchens and built-in mill-work along with trim work, repairs and occasionally some furniture. I enjoy the design and building process and the satisfaction that comes from building things with my hands.I have been in business since 1986

"Very thorough with good finish."

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!"

DNJ Home Improvements is a small owner operated company. We are located in Malverne NY and provide services throughout Nassau county. All work is performed by David and Joe to ensure quality is always great. Uses licensed subcontractors for all electrical and plumbing jobs.

"David and his team did amazing work. Went down to the studs and transformed my basement into a well insulated, cosy living space. Framed out and added a separate Laundry room as well as a huge walk-in pantry. Added a new sturdy staircase, and waterproof vinyl flooring. Added all new doors and wired in an in-wall speaker system. David always worked clean and was extremely reliable. When he was done all we had to do was move furniture in and enjoy the space he created for us."

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.

Yes, insulated vinyl siding increases the R-value of your home. Depending on the quality and brand of the insulated vinyl, you can get an R-value that is up to 5 times greater than traditional vinyl siding. This can be fantastic for homeowners who are trying to lower their utility costs.

While you should always insulate ceilings and exterior walls, you don’t always have to insulate the interior walls of your home to maintain energy efficiency. However, there are benefits to insulating every wall, including improved soundproofing and energy efficiency throughout your home.

Yes, spray foam insulation can be applied to your ductwork and effectively insulate your ducts. Blanket insulation is the easiest insulation product to DIY since it is easy to wrap around ducts. However, spray foam insulation can also benefit your HVAC system if applied to air ducts.

Energy-efficient homes generally have higher appraisals and appeal to buyers.
