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

Make it easier for your inspector to do a thorough assessment by preparing your home ahead of time. That includes:

  • Noting any signs of pests around the home

  • Removing obstacles in the way of the attic, basement, plumbing, garbage, and other key areas that inspectors will need to access

  • Keeping children and pets away from inspection areas

Structural problems with the foundation or roof, water damage, and significant plumbing or electrical issues are all considered major red flags in a home inspection. Of these, a structural problem related to the foundation is often the most severe. Foundation repairs are typically the most expensive and intrusive to carry out, averaging around $5,000 but sometimes reaching up to $16,000. Because these problems can pose safety risks and be costly to fix, you should ask your inspector detailed questions about any identified issues. You will need to carefully consider how major problems affect what you’re willing to pay for the home, or if you want to proceed with the sale at all.

Beyond looking for visible signs of mold in a home, you can tell if your house has mold by undertaking testing. You can hire a local mold testing company to run the test for you, giving you a sure answer. Professional testing is often the best way to determine whether you have mold, as some types of mold may grow in places where you can’t easily see them, such as behind walls.

In some cases, a home inspector tests the indoor air quality if properly certified. Most of the time, however, they’ll outsource the work to a professional air quality consultant. Testing indoor air for pollutants requires several certifications and a suite of specialized tools. Many HVAC and home inspection pros have this certification.

The telltale signs that your home is ready for repointing include visibly damaged bricks, crumbling bricks, flaking bricks, loose mortar, cracked mortar, gaps between brick and mortar, leaking inside your home, and visible water damage. Consider repointing when going over brick house pros and cons if you're buying a new home. Repointing is also a good idea if you plan to paint, acid wash, or stain your brick home, as it will give you a good base for coloration and prevent repairs after the work is done.
