Pumps and Well Service Water Treatment and in-depth trouble shooting. Often Beyond Pumps can solve problems other companies cannot. Beyond Pumps also has emergency generator services. Our team has licensed electricians, a civil engineer, water treatment operators, and years of experience in well work.

"We were having a lot of air in our well system. Causing the water to spit and sputter when we turned on the tap inside. They came out quickly and fixed the problem. It’s been a couple weeks now and it’s been so nice not having to go manually purge the air from our tank! Kind and courteous and highly recommend them. We are having them come back to install a water treatment light into our system next."

Subcontractors questions, answered by experts

No, builders and general contractors don’t expect tips. In fact, some companies may prohibit their employees from accepting client tips. If you want to show gratitude for a job well done, consider writing a review of your builder or contractor or agreeing to be a reference for potential new customers.

Yes, you can finance new construction using a construction loan or a construction-to-permanent loan, or you can use a home equity line of credit or a cash-out refinance if you’re building a second home. Some mortgagors may have restrictions on DIY house builds, so be sure to check that you can get financing before starting your project.

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.

A construction lien results from unpaid services. For instance, if a homeowner hires a contractor to do a large renovation on their home and then fails to pay for the services and materials, the contractor can take out a lien on the property. This lien is a legal claim against the property for the amount of money owed. If the homeowner does not pay their debt, the lien may stay on the title until the homeowner tries to sell and cannot do so until the title is cleared.

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.
