They're pretty friendly, and they help out. They don't waste your money or your time. Last time, they came out for a plumbing inspection and to fix a drain. I do have a service agreement with them, and they did it a couple of times before. I have the plumbing and electrical with them. I would recommend them to family and friends. I'd give them an A+.
We always have a good experience working with Oliver. They come in, and they get right to what they're doing. If something does go wrong, you call them, and they come back. It works for us. They do an inspection. We belong to a couple of their plans. They come in and install new receptacles. I don't remember all the stuff they do. Basically, we have them go through the house. I understand they're going to find something no matter what, but there is no pressure on you to get it done. Usually we do because it's to our advantage. We set a time, they come back, and they do it. We've had them for plumbing, and they've serviced our air conditioner. We've been using them for more than five years. We've used a lot of other electricians and plumbers in the area, and we're just pleased with Oliver. They're an A.
They're pretty good, and they're pretty prompt about getting here. They work on our furnace and check our air conditioning. They put a new furnace in and a new hot water heater. I have been using their services for a long time. I'd give them an A.
He knew what he was doing, he was on time, and he was very professional. He came and replaced a 50-gallon hot water heater. We have a service agreement with them. We get our air conditioner maintenance service every year. I would recommend them to family and friends if they lived out here. I'd give them an A because they were fine.
They did it within the time frame they said they were going to do it in. They were fast, and they were accurate with the estimate. They did an installation of a kitchen faucet. I've used them in the past. One of the plumbers that I had been using purchased Oliver, so I just went to them. I would give them an A grade.
They're friendly, they appear to know what they are doing, and they get the job done. They put in a new hot water heater. They also do seasonal maintenance for me. I don't remember how I heard about the company originally—it's been years. I recommend them, and I'd give them an A.
Everything was easy and smooth, so it was fine. They brought in a water heater for me. I'd rate Oliver as an A-level company.
They were very, very pleasant. They had very pleasant people working for them, and they got the job done. All was good. They had to put a new piece in under the sink where the little faucet had broken off. He was very efficient. They did it fast, and they did it well. I think I first heard about them through my neighbor. One of the other condo owners had recommended a local company, but in the meantime, that local company had been bought out by Oliver. It was kind of a roundabout way, but that is how I found out about them. I would recommend them to others. They're an A.
It was straightforward. They replaced some old valves. It took a few hours for them to complete the job. I would give them an A-.
They're pretty prompt, and they do the job. They've been reliable. We've used them for years. The most recent thing they've done is a plumbing repair. It was a pipe in the bathroom. I chose them over a different company because they put the heater in the house that I live in. I'd give them an A-.
