Why Pay Twice?

Why pay twice for your home, building, condo, and co-op inspection?Why risk having a low-cost or inexperienced inspector tell you, "only a Licensed Engineer can tell you if this crack is structural".

We are often asked to perform an inspection after a non-Engineer has performed a home inspection. The non-Engineer's report stated, "Assessing the structural integrity of a building is beyond the scope of a standard building inspection." Assessing structural integrity is within the scope of a Professional Engineer's inspection.

Structural System

Home Inspection: Structural SystemOne of the biggest concerns of home and building buyers is the structure. Fortunately, structural defects are less common in the Metro New York area than in some other parts of the country. Building codes help limit the number of structural defects.

If you buy a house or building with a structural defect, the fact that most buildings in this area do not have structural defects is of little comfort. You want to know if the home or building is structurally sound. Heimer Engineering's℠ Licensed Engineers provide you with this information.

Some home and building buyers believe structural defects are only a concern in older buildings. Other real estate purchasers feel they can find structural defects by "looking carefully". Still other home and building buyers feel that an old house that is standing must have no structural defects.

There are non-Engineer home inspectors who advocate the "bounce test."  They jump on the floor and if they do not feel the floor bounce, the house or building is declared structurally sound. In the State of New York, only a Licensed Engineer can render an opinion as to whether a home or building is structurally sound. Do not be fooled by someone offering the "bounce test".

Water in the Basement

Home Inspection: Water in the BasementHome and building purchasers are concerned that basement water indicates a structural problem. Most foundation walls have cracks, but basement water does not necessarily indicate a structural defect. Heimer Engineering's℠ Professional Engineers advise you as to whether foundation walls cracks are structurally significant.

Most houses and buildings do not regularly have water in the basement, but are damp during part of the year. If the basement is damp, it may affect your ability to store personal belongings. Basement dampness is a concern to people with allergies or other medical conditions because dampness can increase the risk of mold.

Most houses and buildings are not inspected during heavy rain. When inspecting a house or building on a dry day, our Professional Engineers look for water evidence in the basement to determine what you can expect during a heavy rain or with melting snow.

Heating System

Home Inspection: Heating SystemHouses and buildings in the Metro New York area have a heating system. The heating system keeps the home or building comfortably warm during the winter months. In many newer homes and buildings, the heating system and air conditioning system are combined.

The most common types of heating systems found in homes and buildings are forced hot air, hot water (or hydronic), steam, and heat pumps. The fuel for the heating system can be oil, gas, or electricity.

You need to know whether the heating system will adequately heat the home or building. Heimer Engineering's℠ Professional Engineers assess the sufficiency of the heating system. Our Engineer also assess the age of the heating system, if there are hazardous conditions, if the heating system is outdated, etc.

Hot Water System

Home Inspection: Hot Water SystemHot water is used for bathing and cleaning and serves a vital role in maintaining good health. The hot water must be available at an appropriate temperature.

Homes and buildings have a tankless hot water heater, a hot water heater with a storage tank, a hot water booster tank, or an indirect-fired hot water heater. It would be frustrating to move into your new home or building, and find that you do not have enough hot water the first time you shower.

Heimer Engineering's℠ Professional Engineers evaluate the hot water system and advise you if it is sufficient. You are also advised of the need to budget for upcoming replacement of the hot water system.

Plumbing System

Home Inspection: Plumbing SystemPlumbing describes different systems in a house or building. Plumbing means fixtures such as a sink or tub, the pipes that supply water, the pipes that drain the sewage, the gas lines, underground sprinkler systems, and heating pipes. Heimer Engineering's℠ Professional Engineers check the plumbing for function, leaks, sufficiency of water supply, etc.

One concern of many home and building purchasers is plumbing leakage. Water dripping from a pipe is an obvious leak. Other types of leakage can be difficult to detect, since all that is visible is a stain. Our Professional Engineers inspect for both obvious leaks and difficult to detect plumbing leakage.

Roofing System

Home Inspection: Roofing SystemThe roof keeps rain and other weather elements out of the house or building. Heimer Engineering's℠ Professional Engineer evaluates the roof and estimates the remaining life on the roof. Evidence of past or present roof leakage is also assessed.

Most roofs are made of asphalt, slate, or clay tile. If the our Engineer finds that a roof leaks, needs repairs, or will soon need replacement, an expense analysis of the needed repairs and replacement is provided.

If the house or building has an accessible attic, our Engineer examines for roof leakage and sheathing damage. Our also checks for insufficient attic insulation and ventilation.

Some Home Inspectors advocate walking on pitched asphalt, slate, and terracotta tile roofs. There are Home Inspectors who lift asphalt roof shingles to determine how they were installed. This damages the roof. The slates, cedar shingles, or terracotta tiles suffer damage that can causes leakage.

Asphalt roof shingles are self-sealing. Lifting an asphalt roof shingle damages the seal. Roofing manufacturers will void a roof warranty if they determine damage was caused by an inspector on the roof.

Our Professional Engineers determine the condition of the roof by visual examination. If an Home Inspector needs to walk on the roof or lift the shingles, you should ask; Why can't this Home Inspector determine the condition of the roof visually?  Can't this Home Inspector see that the roof shingles are old?

In some cases, it is not possible to safely observe the roof. If the roof is not visible, we us available satellite images of the roof to assess the roof. This includes historical satellite images, which can allow the roof history to be determined.

The myth of needing to climb on a roof or use a ladder to view the roof came from roofers who went into the home inspection business part-time. Today, very few Home Inspectors climb on the roof or use a ladder to check the roof.

Electrical System

Home Inspection: Electrical SystemA modern house or building requires electricity to run systems such as lighting, heating, hot water, appliances, the air-conditioning, etc. Because many appliances require electric power, some existing homes do not have enough circuits to support modern electrical demands.

Homes and buildings with insufficient electric service may not be old. Even a house or building constructed 25 years ago may not have the electric wiring to support the today's electrical needs.

Electric service insufficiency is aggravated by owners who add appliances without upgrading the wiring. If a home or building owner adds appliances without upgrading the electric service, a hazardous condition may be created. Heimer Engineering's℠ Licensed Engineers check for sufficiency of the electrical system, and look for other wiring deficiencies.

DangerOnly a Licensed Electrician should open a circuit breaker panel. A Licensed Electrician can correct hazards created by opening electrical panels. A responsible Home Inspector will not open electrical panels.

Communities require electricians to be licensed, and prohibit anyone other than a Licensed Electrician from performing electrical work. (Exceptions are made for homeowners wiring their own home.)

Our Professional Engineers determine the condition of the wiring by visual examination. The question is why do some Home Inspectors insist on opening the circuit breaker panel when it creates a hazard.

Home Inspection: TermitesTermites can structurally damage a building. Years ago, it was considered sufficient to have only a termite inspection performed before purchasing a home or building. If there was no evidence of a termite infestation, it was incorrectly assumed the building had no structural damage.

A termite control specialist can look for evidence of termite activity, but cannot assess the structural impact of termite damage. Heimer Engineering's℠ Professional Engineer assesses the structural impact of termite damage. If repairs are needed, the expense analysis in the inspection report helps you understand the cost factor.

Termite control specialists and Professional Engineers look differently at termite evidence. Professional Engineers look for the impact of the termites and termite damage. A termite control specialist is looking at the need for termite treatment. You should have the house checked for termites by both Heimer Engineering℠ and a termite control specialist. This maximizes your chances of finding termite activity and damage. You should also obtain a warranty against future termite activity from the termite control specialist.

Termite Info

Who Can Inspect
for Termites?

Licensed Engineer Termite InspectionsYou will see statements such as New York licensed termite inspection, New York approved termite inspector, New York certified termite inspector, etc. The State of New York neither trains nor licenses termite inspectors. The State of New York licenses pesticide applicators and technicians, not termite inspectors.

We inspect for evidence of termite activity as part of the pre-purchase inspection. The Professional Engineer knows about termite evidence, what conditions invite termite activity, where termites are likely to be found, etc. In addition, our Professional Engineers check for structural damage caused by termites.

Leaks and Thermal Imaging

Thermal imaging and home, building, condo, and co-op inspections.Some Inspectors claim thermal imaging provides better information than traditional home inspection methods. Claims of an ability to detect leaks and hidden structural defects have been used in home inspection advertising.

Contrary to what some Inspectors claim, thermal imaging cannot detect invisible leaks, concealed overheated wiring, structural defects, termite damage, old pipes, asbestos, or mold. Thermal imaging is looking at the infrared emissions (essentially, the temperature) of an object. Thermal imaging provides no special ability to detect latent defects.

Inspection Photographic Images

These home inspectors fail to point out the limitations of the photographs, or how photographs can adversely affect reports.Photographic images included in a Home Inspector's report may show a gutter draining near a foundation wall, a crack in a path, or siding shingles close to ground level. You never see photographs showing the insufficient electrical service, an undersized boiler, or that a house is structurally unsound.

If you use images to negotiate with a seller, it is the seller's interpretation of the images that you are negotiating with. Photographs in a report work to the seller's advantage.

We provide you with inspection photographs if you request them, subject to our privacy policy. We do not recommend that you use the photographs to negotiate with the seller in most situations.

Is the Home Inspector a
Licensed Engineer?

New York State Licensed Engineer IDMany inspection companies send non-Engineer inspectors when the buyer requested a Licensed Engineer. When you retain a Professional Engineer to perform a pre-purchase inspection, you expect a Professional Engineer to visit the site. It is unethical to send a non-Engineer when you expect the services of a Professional Engineer. Heimer Engineering℠ uses only Professional Engineers to perform pre-purchase inspections.

In New York State, a Professional Engineer can obtain a state-issued identification card. When the Inspector arrives on site, ask to see the New York State Professional Engineer photo ID. A non-Engineer cannot lawfully obtain a State of New York Professional Engineer's photo ID.

Environmental Inspections

Home, building, condo, and co-op inspections and the environment.Some companies imply they provide environmental inspections by pointing out environmental concerns. These Inspectors often have limited environmental experience, and may unnecessarily alarm real estate purchasers.

We point out environmental concerns like other Inspectors. We do not deceive you by claiming the pre-purchase inspection is an environmental inspection.

Pre-Closing Inspections

Pre-closing home, building, condo, and co-op inspectionsA pre-closing inspection helps you find out what changed after the inspection:

  • Furniture and stored material should have been removed, providing access to more areas;
  • Leaks may develop after the original inspection;
  • A system or appliances that were functioning during the original inspection may break;
  • A strong storm, neighborhood construction, very hot, or very cold weather may damage the building;
  • And many more changes can occur.

The best way to protect yourself is a pre-closing inspection. A pre-closing inspection gives you the opportunity to have adjustments made at closing.

Thank you for sending …. He explained everything and was very patient with us.

J…, Suffolk County

I was a little annoyed that … didn't talk much during the inspection. After the inspection, … went over everything. It was obvious that … was concentrating on the house.

L…, Queens

My first deal didn't go through because the sellers backed out. I need another inspection. We loved … Please send … again.

O…, Westchester County.

Thank you for sending…. Not only did he do a great job, but he called me back on a Friday evening because I needed an answer right away.

"…said he was an Engineer. Turns out he only used a computer program written by an Engineer. Now the sellers won't accept anything the guy said. So I need to pay for an inspection by a real Engineer."

K…, Brooklyn

"We hired a Home Inspector. We've lived in apartments since we were married and didn't know better. The inspector said there was a crack in the foundation. The inspector said an Engineer needed to tell me if it was a problem. My broker said to call Heimer Engineering. Heimer sent an Engineer who said it was not structural. Heimer's Engineer also told me that the electrical service was good (the inspector told me to replace it) and that the chimney only needed pointing (the inspector told me to put new bricks on the chimney). And the Engineer cost less, because he didn't test for radon and didn't charge extra for termites. Next time, I'll get an Engineer the first time."

S…, Nassau County

The old house needed work, but it was big and cost less than other houses. The floor was sagging, so I had an inspector come who said he could tell me about the floor sagging. He didn't say a word about the sagging, so I asked him. The inspector told me to get an Engineer to check the floor sag. So I paid an Engineer after I paid the inspector. Good thing, because Heimer Engineering showed me there were serious problems because of the way this 100-year-old house was built. I got an estimate from a contractor for $90 thousand to rebuild the porch and the second floor. No thank you, deal's off. The broker said I was smart to get an Engineer. I'll use Heimer Engineering for the next inspection!
