"WARNING: DO NOT HIRE THESE PEOPLE! To start, we got a free quote on May 4th for a concrete patio. They seemed to know what they were doing and gave us the best price, so we went with it. We should have known cheaper never means better. We gave them a deposit and they told us that the remainder would be due at completion, however, each time they were here, they asked for more money to be given. From the start communication and scheduling was very difficult. It took us awhile to get in touch with Vinnie and to get them to come out to do the work. They would say they would come on X day, then they wouldn't show until a few days later, however, we continued to give them the benefit of the doubt and were beyond patient with them from start to finish. Come pour day, which wasn’t until the end of May, they hired only 2 workers, which we later found out, were not “real masons” They poured the cement and only finished half of it. They left that day with a whole cement slab in our backyard with only half of it “finished” They said they would come back the next day to complete it. Cement patios are supposed to be done in one shot- monolithically, or they will crack. They didn’t show the next day to finish. Days go by and still they did not come back to finish it. So now we have a dried cement unfinished slab in our backyard. We then realized that they poured it against the foundation of our house with no expansion joints, which is not up to code. The few days that passed, it rained a lot and we had huge puddles on the patio- even on the “finished” side- just shows you that they did not know what they were doing and it was completely uneven. Truly unhappy with how things were going, we requested them take out the cement slab, clean the cement that was all over our siding, plant new grass where they killed our grass, and most importantly, refund us our money. At the time, they agreed, but it took FOREVER to get any work or money back. Come June 8th, they finally came back to take out the patio, they took out half of it and refunded half of our money. They also never showed to clean our house and replant grass seed like they promised, but at this point, we just wanted our money back. It is now July 18th and after being ignored by Vinnie for weeks and weeks, we had to threaten them with a lawyer, and complaint to BBB and Federal Trade- and it wasn’t until we did that, that they finally sent us the reminder of our money back. I would also like to add that Eric, the “salesperson” as he called himself was nice to us, but VERY rude to his workers that they hired to do work. He would yell at them and we overhead many racial comments he would say to them and it made us feel super uncomfortable. Again, save yourself and do not hire these frauds."

Our trained technicians symbolize our full commitment to providing you with the most professional services available to your satisfaction. Our severe control standards will ensure that you, our valued customer, receive complete and unconditional satisfaction. Licenses and Accreditations: NJ #13VH05631500 NADCA #007260 IAQA #18814 EPA #RI-18506-10-11833 Our Mission Our mission here at DRX DUCT Air Duct Cleaning in New Jersey is to educate our customers about the Air Duct Cleaning. We offer the uppermost quality cleaning possible and bring this service in such a way that will result in maximum client satisfaction. We have dedicated ourselves to the maximum level of honesty, education, client services, and cleaning measures. These essentials together, guarantee that you will experience a permanent satisfaction of our services.
"I think DRX did a terrible job. The only redeeming qualities were that they showed up on time and were easy to contact on the phone. Once they arrived, they cut a hole in the furnace plenum and attached their truck mounted vacuum. After that, they walked around to all the ducts with about a 10 foot "air whip", which is their only tool for cleaning the ductwork. You may be thinking, what happens if your ducts are longer then 10 feet? The answer is: only the first 10 feet get cleaned! After that, they sprayed some Simple Green (yep, the same stuff you can buy from the hardware store) onto the register covers (this is what they call "sanitizing"). This pretty much concluded the service. Here are some things that weren't done: * Blocking off all the registers that they weren't actually cleaning. This seems like it should have been done, after all you'd want to maximize the vacuum coming through the duct you're currently cleaning. * Cleaning anywhere past where their air whip would reach. * They didn't step foot into the attic where all the trunks are. Combined with the limited reach of their tools, I can't see how any of these would have gotten clean. * They didn't even remove any of the register covers. That should give you an idea of what sort of tools they use here.. they have to fit through the 1/4 inch gap in the covers. After they left, I took my shop vac and shoved it down some of the registers. I ended up pulling out tons of dirt/rocks/rusty metal. Overall, if you'd like to waste $400, just light it on fire. You'll save time over waiting for DRX to come."

FAQs for chimney liner installation projects in Beach Haven, NJ
While it’s possible to sweep your own chimney, it’s usually not a good idea for two reasons. First, inexperienced DIYers are more likely to miss areas of the chimney, which still leaves the risk of house fire due to the remaining residue. Second, chimney sweeping seems like a simple process, but it’s highly dangerous. Soot and creosote are both carcinogenic and can cause breathing issues and lung damage. If you don’t take the same safety precautions that professionals do, you could be putting yourself at risk of serious bodily harm.
Some of the most common chimney problems include:
Creosote buildup
Chimney blockage
Deteriorating brickwork or stonework
Cracked chimney top
Damaged flashing
Flue liner damage or deterioration
Damaged chimney cap
If you suspect you have a chimney problem, contact a masonry contractor for an inspection.
The average cost for a professional chimney cleaning is around $250, but prices range from $130 to $400 or more, depending on a few factors. Some things that have an impact on your total include the size of your chimney, the number of chimneys cleaned, and how accessible the chimneys are.
The National Fire Prevention Agency (NFPA) recommends chimney sweeping once per year as a means of avoiding house fires and massive property damage. Over time, creosote and soot build up in your chimney from burning wood and a lack of ventilation. These compounds are both highly flammable, which means a build-up of them inside your chimney puts you at an increased risk of house fire. Chimney sweeping removes any residue and helps reduce the risk of property damage and personal injury from fire.
On average, chimney repairs cost about $455. However, because of the vast range of potential repairs needed, the cost to repair a chimney ranges widely from $160 to $15,000, depending on the type and extent of repairs required.
The Beach Haven, NJ homeowners’ guide to chimney liner installation services
