When it comes to new-home construction, there really is no limit as to what can go wrong or not be done correctly during building. Defects are common; in fact, it has been said that a home inspector can sometimes find more things wrong with a newly constructed home than an existing home. This is why it’s important to always have a home inspection when buying a house — even if the house is newly built.
You might wonder what kinds of defects a new house could possibly have. Here is a list of problems home inspectors often find:
Premature cracking and settlement in foundation walls can be caused when builders don’t allow the proper amount of curing time for concrete in poured and block foundation walls and slabs. In addition, improper framing techniques — which may not be apparent at first — can cause cracks to develop in drywall. These are typically hairline in nature.
Our inspectors occasionally discover that the vent pipe from a gas-fired furnace has not been connected and has come loose during the initial operation. This is a major safety hazard, as carbon monoxide may enter the residence. In one situation, the PVC pipes used to vent a gas-fired furnace were not properly glued together. In addition, our inspectors sometimes find thermostats that do not respond to normal functions. Another common problem is missing drip legs on condensate lines.
The list is long for typical electrical problems, and most would not be obvious to the average home buyer or owner. The problem with defects in your home’s electrical system is that most are a fire and/or safety hazard. Here are the most common electrical problems our inspectors find in new houses:
- Missing switch plates or receptacle covers
- Improperly wired outlets
- Open grounds — ground wire is not connected properly
- Reversed polarity
- Open knock-outs in the main electrical panel
- Improper wire sizes on breakers
- Double-taps on breakers in main panels — when two wires connect to a single breaker
Jumpers ahead of the main lugs (double-tapping) — when two wires connect to a single lug
Plumbing problems are something you certainly don’t want in a new house. Leaks can cause major damage and mold issues, while other defects are more of a nuisance. But shouldn’t your brand-new home be free of nuisances? Here are some of the most common plumbing issues:
- Unglued or improperly glued PVC pipe connections frequently develop leaks — you may never know about the weak joint until standing water begins to seep through
- Hot/cold reversed faucets and fixtures
- Bathroom sink drain stoppers that were not connected
- Improperly vented plumbing systems may be noisy and/or smelly
- Drain pipes that were not connected (One of our inspectors really did find a drain pipe in a crawl space that was never connected)
Believe it or not, our inspectors have found all of the following problems in newly constructed houses:
- Incomplete door hardware on closet doors, cabinetry and entrance doors
- Improper fire-rated assemblies for pull-down attic stairs
- Missing handrails on stairs
- Missing or insufficient insulation
- Leaky windows
- Siding defects
- Improper grading, which could lead to water intrusion and foundation damage
What these defects tell us is that if you are moving into a newly built house, don’t skip the home inspection. Even the best builders in your area use subcontractors, so you can’t assume that everything in your house is top-quality just because you builder is. Plus, you have to allow for human error, which is how many of the problems mentioned here happen. So, even if you just had your house built, it’s worth the cost of a home inspection to ensure that everything was done correctly, and that your new home will be safe and worry-free.
