"Hal and I have been working together on several interior and exterior projects over the past three or four years.  The most recent project was the completion of the backyard fencing, including a gate.  As always, Hal expertly managed the project.  The quality of his work is always high.  The fence is gorgeous with Hal's sense of artistry clearly evident.  I find that Hal is extraordinarily conscientious and a very effective communicator.  He and his team are reliable, and Hal actively supervises the team to ensure that the work meets his high standards.  Hal and his team's work is completed quickly and timely, and the work site is always neat and clean.  Hal and his team are very careful to respect my neighbors' property during the tear down and construction phases and to keep my dogs' needs in mind (they always installed temporary fences over night so that the dogs could run during the evening).  It is hard for me to find words to describe the skill and artistry that Hal brings to fencing project.  I recommend referring to his website at www.gardenstructuresandmore.com.
I highly recommend Hal and Garden Structures and More for backyard fencing projects.  Hal listens to me and designs structures that match my tastes.  He provides me with guidance and suggestions that are truly helpful.  I don't spend any time managing Hal's projects or checking his work as I know that Hal has such high standards for his work.  Hal is very good at communicating with me.  I always know the status of a project because Hal has always contacted me before I can even thing about calling him.  In the end, Hal makes it really easy for me to get projects completed, which is something that I value in a contractor.  As an aside, Hal's skills and reliability extend to interior projects.  Hal has built two stair cases, refinished bathroom walls and ceiling, and completed other projects for me.  Hal is very knowledgeable, reliable, and skilled about interior projects.  Again, I highly recommend Hal and Garden Structures and More.

"Well, the first time the replacement was ordered it was the wrong one, which of course, delayed the installation a week. When it was finally installed I had to pay an additional $850 for code upgrades. This I was not informed of by Home Shield. Then we noticed that there was water on the garage floor and found that the pipe coming in from the wall was leaking at the wall so had to call the plumbing company back out to fix it. They first tried to say it was not their fault but since there wasn't a leak before they installed they did fix it. I have used Home Shield a few times before and never had a problem. Some of the companies they use are not the best so you have to research them before you commit. I have found HS service to be good if you do your homework. At the end of the day I was without hot water for almost 3 weeks but it was do to the plumbing company they sent out."

Sump Pump Installation FAQs, answered by experts

If your sump pump isn’t engaging, it might be clogged with dirt and debris. Check to see if the fitting lid is loose and has been letting debris in. Next, check the float and make sure it’s not obstructed by rust or gunk, which results from insufficient maintenance. Tangled wires or damaged switching systems can also stop your sump pump from engaging.

There are a couple of similar alternatives you may consider for a sewage ejector pump, including a grinder pump or a submersible sump pump. Submersible sump pumps protect your home from flooding from outside water, though, rather than handling wastewater from inside. A grinder pump macerates, or shreds, solid waste before pumping it onward to the sewer line.

Costs depend on pump type, labor rates, and the extent of repairs or installation needs.

You shouldn’t shower while a sump pump isn’t working. Although household wastewater isn’t supposed to go into the sump pit, it’s best to wait to shower until your sump pump is running properly and able to move excess water out of the basement. If you need to shower when the sump pump isn’t working, aim for a short shower.

Yes, it’s normal (and beneficial) to have a small amount of water in the bottom of your sump pit. It shows that your system is collecting groundwater, rain, and excess water from around your property—just like it’s supposed to. However, if the sump pit is always full, you might have a leak or a faulty sump pump.
