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."

"It’s not often that a reviewer praises a contractor for what he DIDN’T do. Austin Ireland, the owner and operator of Drytek, didn’t propose spending several thousand dollars on encapsulating my wet crawl space. He said that in my case encapsulation might not be cost effective. You see, my 50 year-old home’s foundation consists of 8”x 8” wood posts, with the foundation’s perimeter enclosed by 1”x 6” boards, slatted to allow for ventilation. The layout of my irregular crawl space posed other installation problems as well. Among other things, insulation panels would need to be installed to form walls in addition to the vapor barrier and a large dehumidifier. Four contractors/salespersons preceded Drytek’s Austin Ireland. One simply said there’s nothing that can be done. Another proposed encapsulating the crawl space from the OUTSIDE, but thankfully never followed up. Another did an evaluation, but never returned my calls. Dryzone wanted $8,500 but offered a pressure tactic $425 discount if I signed a vague contract the same day the salesman came. Later the salesperson said the installation of insulation boards would raise the cost significantly. The salesperson at Dryzone also said he would call back with details, but didn’t. Drytek’s Austin Ireland, on the other hand, took more time than any of the others to carefully examine my crawl space. I crawled with him as he pointed out the condition of my crawl space and the challenges of encapsulation. By this time, my own research had better prepared me to better evaluate proposals. I found him to be knowledgeable, straightforward and honest. I was a highly motivated prospective customer. Last year a HVAC system had been installed with the air handler, electronics, and ductwork in my crawl space. The moisture in the crawl space last summer was degrading the new system. So what did Austin Ireland of Drytek propose? Four centrifugal snail fans joined together by extension cords, placed strategically in the crawl space. These are not exhaust fans to ventilate, but rather air movers like you may have seen in public bathrooms to dry floors. He even showed me what to do, and wouldn’t take any payment for his visit. After investing $400 the next day at Home Depot , I located the fans, connected the extension cords to the receptacles in the fans and waited for the heat and humidity to test Austin Ireland’s theory. It is now six weeks later and we have had three prolonged periods of hot, humid weather during which I have activated the fans. THE CRAWL SPACE HAS STAYED AS DRY AS A BONE. Amazing! The vast majority of wet crawl spaces need to be encapsulated; mine did not. But it took a trustworthy expert whose ethics mattered more than profit to present the best solution for me. Austin Ireland, owner and operator of Drytek, is that person."

We are a small family owned business that has been operating in Worcester County for almost 11 years now. We do most of our work in Ocean City, West Ocean City, Ocean Pines and Berlin. In the off season, we will take on some jobs in the Fenwick Island to Bethany Beach areas. We are honest, reliable and promise to return all calls no matter how busy we are. If we can't get to your job, we will let you know up front. We have a long list of referrals and keep digital pictures of each of the projects we have completed. During each project, we keep our customers up to date on the progress with daily emails and pictures. We have earned the trust of over 98% of our customers and they have asked us to hold on to a set of keys for their unit. With 75% of our property owners being from out of town, we can be there for them in times of an emergency or bad weather such as hurricanes and nor'easters. Before, during and after a storm we can monitor the condition of their properties and keep them posted. We have become very efficient in solving water damage problems over the years. We specialize in the treatment and prevention of mold due to water intrusion. As far as subcontracting, we try to stay away from it as much as we can. The only thing we sub out is electrical, plumbing, HVAC and roofing. We only deal with highly professional licensed companies that have been working in our area for over 10 years. We love referrals, but we love it more when a new customer gets to talk with an existing customer.

"HORRIBLE CONTRACTORS!!! I have had contractors before and experienced some issues but this Anthony guy is very unprofessional and he is an absolutely nightmare! Not a single item was completed from the contract he and I agreed on and he took 60% of the contract amount and he stopped working the property. I had a property with some cosmetic work stuff and repairs which shouldn’t be that complicated. After he toured the property and gave me estimated time frame for 2 weeks. I know normally how it is not done with contractors so I asked him a few more times and confirmed if he could really finish it in two weeks. He was confident and said two weeks for no problem. After it has been almost 4 weeks, not even a quarter of work has been done and I noticed he didn’t even show up. He has so many excuses and complaints every single time when I contacted him. It felt like he was working for free which was not true. We agreed on 3 installment payments, 1st installment, before the job start about 30% of the total price, and 2nd one, 1/3 of the total price, and the last one at the completion of the job. After 2 weeks of work and not much of work has been done, he already requested for the 2nd installment. I asked him, the work has not been done 2/3 of the job, more over not even half way done. Anyway, he got upset and he wouldn’t continue the job if I didn’t pay. So I paid and then BOOM! He didn’t show up at work and when I asked him, his answer was it is too cold to work at the property. He made excuses and excuses and he said he will only come back if the heater is fixed. I did and texted him and called him. NO RESPONSE. Besides, his quality of work is horrible. He and his crew painted all over, light fixtures, light bulbs, floors, even bathtub. What kind of painter paint over the tub?! They simply didn’t even covered the parts not supposed to paint but they were so lazy and sloppy worker. They installed the brand new room doors, two out of three, didn’t even close properly and didn’t even use the shim. Installing the door is one of the basic carpentry job and he can’t even do that! I asked for the breakdown of the work and cost and no answer. When I confronted him for a few stuff, he just blah blah blah and repeating himself by making endless nonsense and not doing the job at all. Even if he does a job, not a good quality one."

Insulation questions, answered by experts

The best time to insulate a garage ceiling is when the weather is mild and dry. That means it shouldn’t be stormy, snowy, or raining, and the temperatures should be comfortable. Ideally, you’ll insulate your garage ceiling in the fall, before winter hits. Not only will you be the most comfortable, but you’ll also likely see the greatest energy savings heading into the colder weather with a newly insulated garage.

If you have access to the foundation walls, adding spray foam insulation to your existing unfinished basement or crawl space is straightforward. Replacing existing insulation in your unfinished attic space is possible after removing the old insulation. However, spray foam insulating an existing wall after the drywall is in place isn’t possible unless you remove most of the drywall.

The level of insulation is determined by both the material and the thickness of the door. Some garage door materials (such as wood) have natural insulating capabilities, while other materials (such as metal) do not. No matter the material, two-layer and three-layer garage doors have a higher R-value than single-layer garage doors, as insulation is fitted between the panels. 

It's essential to use insulation materials specifically designed for air ducts. Common types of duct insulation materials include fiberglass, foam board, and reflective foil. These insulation materials have the right properties to withstand the temperature and airflow conditions within the ductwork. Using the appropriate insulation not only ensures efficient temperature control but also prevents potential safety hazards or the release of harmful particles into the air.

A dehumidifier can reduce condensation on your ductwork by lowering humidity levels in the air. Condensation occurs when humid, warm air makes contact with cold ducts. A dehumidifier can help maintain your home's indoor humidity below or around 50%, minimizing moisture buildup. However, if condensation is caused by leaks, cracks, or other damage, a dehumidifier won’t solve the problem.
