Jones Services is now a NO CONTACT service company. Our plumbers, electricians and HVAC technicians are running NO CONTACT service calls. We literally stand in different rooms than our customers, emailing or reading out loud our findings. No handshakes, no paperwork, not even allowing customers to touch iPads. Our technicians wear disinfected gloves, use disinfected tools and whip down anything their gloves and tools touch after servicing equipment. We practice NO CONTACT at work now too. Technicians are not allowed in the office, equipment and parts are delivered to their trucks in the parking lot. Only one employee per vehicle. All company meetings are conducted via Zoom. Most office personal are working from home. Those in the office work apart from each other. No one wants to be quarantined with their toilets backing up, without water or electricity or heat or hot water and now without air conditioning or air filtration or air purification. We are doing everything we can to help all our employees stay health to protect ourselves and our customers.

"HVAC service was amazing from Jones Service. From start to finish everything was perfect. The price was very competitive. Love their work."

"Needed replacement of toilet wax seal. Service tech and assistant were super-nice, professional and clean. Said it would take 2 to 2.5h, but took about 45mins and the charge was $550 + fuel surcharge (if flange was not damaged). I thought this was quite high but based on Webber's ratings I figured it had to be right. Later found out that a experienced plumber would only charge around $200. Too bad, will not use T Webber again."

"I had a frustrating experience with a previous electrician who didn’t install my Generac properly, so I reached out to Randy and his team at Lehland Electric. From the start, they provided a fantastic quote for a brand-new Generac system along with baseboard floor heaters. The team was professional, completed the work on time, ensured everything was up to code, and now everything runs perfectly! It’s clear they really know their stuff. What stood out the most was their genuine approach and reliability. It’s such a relief to finally have an electrician I can count on!"

Total Plumbing offers a variety of plumbing services to meet your needs. Our family owned business guarantees your satisfaction. Services offered include, but are not limited to, hot water heater installation and repair, water softener installation, plumbing leak repairs, and new appliances and fixture installation. Contact us by phone, text, email, or the Angi app to schedule an appointment to service your plumbing needs.

"⭐️⭐️⭐️⭐️⭐️ Kevin at Total Plumbing is the absolute best! Our Navien combo system was acting up, and another company (T Webber) told us it needed to be replaced entirely—for $7,000—even though it was still under warranty and this fee was just for their labor! Thankfully, we called Kevin for a second opinion, and we’re so glad we did! Kevin quickly identified the real issue and assured us the unit didn’t need to be replaced, just repaired with a few new parts. He fixed everything for a fraction of the cost and saved us thousands of dollars. His honesty, expertise, and professionalism are unmatched. Thank you for being so reliable and trustworthy, Kevin! Highly recommend Total Plumbing to anyone in need of an honest and skilled plumber!"

Subcontractors questions, answered by experts

In most cases, a contractor will ask you for a deposit that is a percentage of the total cost of your job, but you should never pay in full before work has begun. The up-front cost could be as much as 50%, or you might give a contractor as little as 10% up front. Discuss payment terms with your contractor before they begin the job to avoid surprises.

It pays to hire a project manager or general contractor when you have a large-scale project that will take over a week to complete, especially when it involves structural changes and multiple subcontractors. This includes hiring a general contractor to build a house, add an extension, or manage other projects that need a building permit.

Common pitfalls include underestimating the cost of site preparation, overlooking permit and utility fees, and not setting aside funds for unexpected changes. Change orders during construction can disrupt your budget. It’s best to plan a detailed budget, obtain multiple quotes, and include a 10% to 15% contingency fund for unexpected expenses.

Many providers assist with obtaining necessary permits. Confirm with your contractor.

Whether it's better to buy or build a chicken coop depends on your priorities. Do you want to save money? If so, then you should build your own chicken coop because it will cost much less—about half—than buying a chicken coop. If you want a perfectly constructed coop with all the bells and whistles without sacrificing your time and energy, it's better (or at least easier) to buy one.
