Frequently Asked Questions

Can LJM Construction handle demolition and septic work as part of the same project?
Yes, that's one of the main advantages of working with a multi-trade contractor. If an old structure needs to come down before a new septic system can be installed, they can manage both phases without you hiring separate crews.
How do rural Hillsboro properties typically affect septic system design?
Hillsboro's rocky, varied terrain can limit where a drain field can be placed and how deep excavation can go. Soil testing and site evaluation early in the process help determine what type of system will work best for your specific lot.
What's the difference between a conventional septic system and an alternative system in NH?
Conventional systems use a tank and gravity-fed drain field, which works well in areas with suitable soil and drainage. Alternative systems, like mound or pressure-dosed systems, are used when soil conditions or lot size don't support a conventional setup, and they're common in New Hampshire's rockier regions.
Do I need a soil test before a new septic system can be installed?
Yes, New Hampshire requires a soil evaluation as part of the permitting process for new septic systems. This test determines how well the soil can absorb and treat wastewater, which directly affects what kind of system gets approved for your property.
How often should a septic tank be pumped in central NH?
Most households should pump their tank every three to five years, though larger families or heavy water use can shorten that interval. Regular pumping prevents solids from overflowing into the drain field, which is a much more expensive problem to fix.
What happens if I ignore a failing septic system?
A failing system can contaminate groundwater, create health hazards, and cause sewage to surface in your yard or back up into your home. Beyond the health risks, letting a problem go too long often turns a repairable issue into a full system replacement.
