4 Service Pros

4 Service Pros


I was so pleased with Jimbo Mulligan’s plumbing knowledge and expertise that I wrote a review on his estimate alone. Now that the work is done today, I write again….You must call 4 SERVICE PROS first for your plumbing needs! JIMBO MULLIGAN is a plumber par excellence!
I used 4 Service Pros the first time when my 90-yr old mom’s house needed a new gas hot water heater and there were also several other things going a wry, plumbing-wise. Jimbo came out today and took care of installing a new Pressure Relief Valve (PRV) and had to do some work to update the existing pipe in this 64-yr old house. Excellent work! I think Jimbo is so good because he knows his plumbing, gives the customers 5-star work because he cares about his work and it shows! When he came to do the estimate of the plumbing issues, one of the issues was a leaking bathroom sink faucets. He told me that the faucets needed to be replaced due to not being able to get replacement parts due to a non-standard brand was installed when the bathroom was redone. He also noticed that the hot and cold water supply lines needed to be replaced. They were so bad, they were an accident waiting to happen! He installed a Studor Vent for my mom’s walk-in tub that hasn’t drained properly since it was installed. Overall, Jimbo Mulligan can look at your plumbing issues, explain to you what is going wrong, advise you on the best way to fix the issue and if you have a long list like me, he can also give you advice on the best way to prioritize the work based on the plumbing issue, your time and finances (if you are upfront and honest with him). Ask for JIMBO MULLIGAN as he is truly a man of integrity, honest, kind, professional and knowledgeable! With the plumbing side of 4 Service Pros being top-notch, I know that, without hesitation, I can call 4 Service Pros for any HVAC, Electrical or Remodeling issues! Don’t wait, call 4 SERVICE PROS NOW and ask for JIMBO MULLIGAN!
Excellent Company. 3 men - John, Maurice and Nelson - came to the rescue after I made an appointment. They were charming, friendly, courteous and above all excellent, knowledgeable and simply great. I am so glad I found this company, gives me peace of mind to know that I can rely on them for future projects should they arise. Oh yeah, before I forget - scheduling is a pleasure - none of this *press 1 if you want blah, press 2 if you want blahblah.......*. And they were on time, giving me about a 30 minutes phone notice about
their exact arrival time.
4 Service Pros did a phenomenal job. My wife and I could not have picked a better company to do the work. Every one of the workers were always professional, prompt, knowledgeable, paid attention to detail, hardworking and very friendly.
Minh was the lead (supervisor), he is very meticulous, has a keen eye and pays attention to details. He was always available and ready to lend a hand to his workers and check up on their progress. If we had any questions or concerns, Minh was always responsive to us and very honest in his opinions, he didn't just tell us what we wanted to hear but gave us his honest assessments. Some of his suggestions saved us money.
I Would like to also point out the two main workers, Eliqzar and Shane. They are very hard workers, friendly, but professional. Eliqzar and Shane did the bulk of the work and were also very meticulous about the work they were performing. The same applies to Peter the Electrician and the two Plumbers, Rick and Carlos. It was obvious that everyone enjoyed their work and was proud of what they were able to accomplish.
Two additional people that I would like to point out is Sender the Flooring and Rug installer and Joel the Painter. Both did an outstanding job, the flooring and rugs look awesome and the painter Joel is amazing, the walls and ceilings never looked better. My wife and I were truly impressed by Joel and the amazing paint job he did and how hard he worked. I would not hesitate to recommend Joel and Sender if anyone is looking for a Painter or a Flooring and Rug installer.
All in all, we couldn't have had a better company to perform the work. We can't say enough good things about 4 Service Pros, the entire house looks like a brand-new house. I would hire 4 Service Pros again.

One of the best companies in the area with Great service and staff. Thank you
I had a problem with backed up sewer water that needed a new ejection pump. Carl at 4 Service Pros came out the same afternoon and put my n a new pump for me very efficiently! Great service!
Technician called and arrived within half an hour from the time he called. He introduced himself and then looked over the problem area. At that time he gave me an estimate of the cost. He went right to work and not only installed a new garbage disposal, he also corrected errors left from pass work that was not done correctly. He was courteous, prompt, and efficient. Most importantly, the total cost was not one penny more than that which was quoted. I certainly will be calling 4 Service in the future for my plumbing needs.
Five stars! I had a serious leak in the underground, 120-foot, water pipe leading to my townhouse. They replaced the polybutylene plastic with a copper pipe. Dave, Rick, and office staff were very service oriented. Once the problem was diagnosed, response time was fast and professional. They kept me informed throughout the process, back-filled the trench, planted grass seed, and cost was below other quotes. I would highly recommend them.
Thank you to 4 Service Pros. I came home after a Vacation to a water main break. David J and Bobby came on a Sunday and repaired it.
We hired this company to install an attic fan. During both the estimate and install phases, they arrived on time (that's a big plus) and were personable and professional. Work was done quickly, with no mess left behind and while on the roof, found what could have become a major problem, and fixed it free of charge. Post install, an inspection of the plumbing and electric uncovered some issues that need attention and estimates for those were quickly sent.
We will be using this company again for the most serious of these matters.
Five stars from us.

In 1989, NASA performed a study on plants to find out if they provide a natural way of removing volatile organic pollutants from our indoor air.

Since then, the study has been replicated and the results stated that "future research is needed to fully understand indoor VOC removal by plants."

Read more about it at the link below. There is also a list of the plants they studied and the results of each.

Have you heard of a hypocaust?

A hypocaust is a central heating system in a building that produces and circulates hot air below the floor of a room, and may also warm the walls with a series of pipes through which the hot air passes. They were even used to heat bathwater!

The word is derived from the Ancient Greek. Hypo meaning "under" and caust-, meaning "burnt" (as in caustic).

The earliest reference to this type of system suggests that the temple of Ephesus in 350 BC was heated in this manner, although Vitruvius attributes its invention to Sergius Orata in c. 80 BC.

Its invention improved the hygiene and living conditions of citizens and was a forerunner of modern central heating.

How many filters do you have in your house?

A. Just one!
B. 2-3
C. 4-5
D. 6+

Many homeowners have just 1 filter located right next to the heater or air handler.

In other cases, homeowners have filters at their return vent(s).

Wherever your filter is located, make sure you're changing it regularly!
