"AJ had come to our house a few years ago for the estimate on the crawlspace. We also had one other company out for an estimate at that time. After meeting AJ we knew we would hire him because he also walked around our yard with us to suggest improvements with yard grading and other suggestions to keep water out. He was also upfront about the cost and work to be done. He didn't try to sell us on any gimmicks or anything we didn't need. AJ stands behind his work and is very knowledgeable and experienced. We did not go ahead with the project after the original estimate because we decided to put that project on hold. We needed to attend to our leaky roof and other home projects. However, when it came time to get the work done we called AJ without hesitation. Everything went great. AJs workers sealed off the areas in our basement where they were working and when they were done everything was cleaned up as if they were never there! AJs team removed several inches of dirt, stones and debris from the crawlspace floor. A French drain with a sump pump was installed and the walls of crawlspace were done over with concrete of AJs particular waterproofing blend. Additionally, hangers were installed on a sewage pipe which ran though the crawlspace. This was done because the pipe was supported by concrete blocks which needed to be removed in order to install the french drain. Now the crawlspace is in absolutely wonderful condition and Ill have piece of mind every time it rains. I can highly recommend AJ waterproofing."

"After being on hold with another local well-known company for over five minutes, I was pleased to have my call answered right away by Mattioni's. They sent a technician out right away, gave me a reasonable/high estimate; explained the need for the expansion tank and the gas pipe grounding. Work was done later that day. Technician was a bit chatty, and did need to return the next day to fix a very small leak, which they did for obviously no charge. All in all, we were pleased, and would use them again.

Drain Pipe Installation FAQs, answered by experts

Drain fly problems can go away on their own—but only if the insects find the environment inhospitable. Those with a minor infestation can simply flush their toilets and run their faucets more frequently to flush out the flies and larvae. Others will have to deep clean their drains and set up traps.

You can drain a hot tub very quickly by using a submersible pump rather than the hose-sized drain at the bottom exterior of the tub. A pump can move up to 30 gallons per minute, draining your hot tub in no time. Using the regular drain can take up to two hours.

You can try several easy methods to unclog a drain, one of the easiest and most effective of which is to use a mixture of baking soda and vinegar. This will help dislodge and dissolve the clog to move it down the drain pipes. Pour 1/2 cup baking soda into the drain, followed by 1/2 cup of white vinegar. Dump several cups of boiling water (or hot water if you have PVC pipes) into the drain and let sit for up to one hour. Run hot water to clear the drain.

The best way to unclog a bathtub drain is to pour a pot of boiled water down the drain, being careful not to splash yourself. However, take precautions, as boiling water can damage PVC pipes and joints. Follow up with ½ cup of baking soda and ½ cup of vinegar. Cover the drain with a small sink plunger and let it sit for 15 minutes. Pour boiling water down the drain again and replace the drain stopper.

Common causes include hair buildup, soap residue, food particles, and foreign objects. Older pipes can also contribute by facilitating buildup more easily.
