Customers say: True professional

"This was an appraisal of a older condominium unit in a gated Southern California beach community for a trust administration. Unusual in that Penny did not have access to interior of the unit she had to appraise. She was very thorough in her research of the complex, and inspected a similar unit that was on the market, in addition to reviewing prior sales records and condition of the unit she appraised. Her comps were very good and it was clear that she'd done her due diligence to discern the appropriate sales, given the three different areas of buildout in the complex. She made a balanced and fair valuation of the property which was important for me to have as the Trustee, and reported on her considerations in good detail."

"I had Mr. James Beggs appraised one of my properties first and see how he does. I needed the step up in basis appraisal done right away so i would have the report before taxes were to be due in April. Mr. Beggs was able to do the appraisal right away, he arrived on time for our appointment to meet with him, explained my options on the appraisals and had the appraisal report within a few days. I was happy that he was able to do it right away and I was satisfied of his work so i requested him to do my other two properties as well. I requested for him to send me an online and a hard copy report of the appraisals and he did. Im a happy and a thankful client. Thanks Mr. Beggs and thank you too Home Advisor! This is my second time i used this site."

"a different roofing company repaired our roof a few years ago, so when we needed an inspection for insurance, we reached out to Reign Roofing. Adam came out twice—once in the rain and again to ensure a thorough check. We received their report today, and no repairs were needed. They could have easily suggested costly work, but their honesty and integrity stood out. We've trusted them for years and appreciate their reliable, efficient service. It's rare to find a company that truly puts customers first."

Home Inspection FAQs, answered by experts

You can ensure a home inspector is unbiased by doing your research. Verify their work history and certifications so you know they’re qualified to be inspecting your home. Read reviews to understand other customers’ experiences and whether or not they were satisfied with the inspector’s assessment. Interview potential home inspectors and ask how they get their clients. If they’re not dependent on any one realtor for clients, they’re unlikely to risk producing a faulty report just to benefit one agent.

The only way to determine if you have a radon problem in your home is to have professional testing done. You can buy DIY radon test kits, but these are sometimes inaccurate in certain temperatures and humidity levels, and they don’t paint the entire picture in terms of your radon exposure. Scheduling testing once every two to five years is best. You can also look out for the following symptoms, which, according to the American Cancer Society, are symptoms of radon exposure:

  • Shortness of breath

  • Cough

  • Tightness in the chest

  • Difficulty swallowing

  • Hoarseness

There are a few things that can set off your carbon monoxide detector that aren’t an emergency. Low batteries or a malfunctioning system are usually the biggest culprits, but dust and dirt can build up on the sensor and cause issues, too. If you have a single unit that serves as both a carbon monoxide and smoke detector, extreme humidity (like the kind coming from a shower) can accidentally set it off. 

It is generally recommended to schedule a professional plumbing inspection annually, though an inspection every two years may be sufficient for newer homes. The ideal frequency depends on several factors, including the age of your plumbing system, water quality (such as hardness), and any previous plumbing issues. More frequent checks are advisable for older homes or those with a history of problems. Additionally, if your property has mature trees with extensive root systems, more frequent inspections are beneficial as roots can crack sewer and water lines. Regular maintenance helps identify potential issues early, preventing costly repairs, and can include checking for leaks, inspecting connections, and ensuring pipes and fixtures are in good working condition to prolong the life of your plumbing system.

Federal law doesn’t require homeowners to disclose the presence of asbestos in their home, but some states and local municipalities may require it. That is why it’s important to test an older home for asbestos and other health hazards before moving forward with a sale.
