Home or House Structural Engineering Inspections  for home buying or refinancing

Inspections by our Structural Engineers are not typical home real estate inspections.   A common situation that comes up is the requirement by a mortgage company underwriter for a structural engineer to provide a letter discussing the structural adequacy of a building/home. In our experience, this condition arises when a home inspector or property appraiser makes the recommendation to the buyer, seller or mortgage underwriter to get an opinion from a structural engineer. A-1 Engineering has developed thousands of these opinions and is accommodating to have our engineers visit the site, completed the assessment and develop a report in a short amount of time.  

A-1 Engineering can also provide an opinion and recommendations for "retrofitting" manufacture homes that need to be in general conformance with HUD and FHA regulations. The process is the same. Call our office and speak with one of our project coordinator. Explain your situation to us and our project coordinators will assist you in developing the adequate scope and fee for our engineers.

Please refer to our different types of Structural Inspections. And read our popular article on Selling a House with Foundation Problems.

What Kind of Structural Engineering Services do we offer?

We provide a wide range of Structural Engineering Services with our focus in Residential Structural Engineering in San Antonio and Austin, Texas. Within Residential Structural Engineering we provide Foundation Engineering design, as well as home or residential Structural inspections for foundations, wall framing and bracing, and floor and roof framing. We can also provide Structural Engineering design for retaining walls.

                    Retaining Wall Engineers

A-1 Engineering specializes in designing retaining walls with concrete, masonry and segmental retaining walls. Segmental retaining walls are cost efficient walls that are commonly used throughout subdivisions, highways and other developments. They consists of masonry block walls that are dry stacked with stone back bill. They are cost efficient and aesthetically pleasing. We have the experience and training to design walls constructed with concrete, masonry blocks, limestone blocks and timber. Additional information on when you should get a retaining wall structural engineer involved is discussed in the City of San Antonio Information Bulletin 171.

                     Structural Foundation Inspections and Design

The structural Engineering design of Foundations can either be a Structural concrete slab foundation as well as pier and beam type of foundations. 

It's important to know that we are unbiased in giving you our Structural Engineer Report if we see anything wrong with your foundation because we are not contractors so we don't provide the physical repair of the Foundation. Many Structural Engineering Firms out there provide physical repair of Structural foundations (directly or indirectly) which believe means their opinion is biased with an inherent conflict of interest.

If you hire us for your home inspection (i.e. assessment) thinking that you may have Structural foundation problems we'll give you our opinion without having the conflict of interest that many other structural engineering companies or firms have because we don't gain anything by telling you that you have a Structural Foundation problem.

Many times we are called to perform a Structural foundation inspection after another structural engineering company or firm that provides Structural foundation inspection and Structural foundation repair services claims that the house has foundation problems; in fact, many times we are called to perform a Structural Foundation inspection after even two Structural foundation repair companies have been called to inspect the Structural Foundation and they provide dissenting view on the mater. In other words, we're called as an independent third party structural engineer to perform a Structural Engineering Foundation inspection and give an independent opinion... Many times there's nothing wrong with your concrete foundation and the structure of you house! Save yourself time and money by hiring us first as your primary Structural Engineer and let us give you a recommendation of whether you need to hire someone to repair your foundation. Please read our article on Foundation Repair.

Just because you have cracks in your concrete foundation it doesn't mean you have foundation problems. The nature of Concrete is to crack, the real question is, is the concrete foundation cracking because of temperature and shrinkage, or is it because of soil movement below the concrete foundation? Again, an experienced structural engineer, who doesn't perform repair services, is the best structural engineer qualified for a non biased foundation inspection. But even if it is cracking due to Foundation Movement, the crack themselves may not indicate actual foundation failure.  

We can also provide you with wall bracing letters for the City of San Antonio Texas advising the city that the structure is safe. 

Many times we've worked with Banks, Mortgage brokers, Realtors and Homeowners, in providing home or residential structural inspections. We are also very fast in providing you with our Structural Engineer Report.

If you're looking to get some  sort of warranty for your Foundation we recommend this Structural Engineer San Antonio tx
