Essential Questions to Ask Your Stamford Concrete Contractor

Licensing and Insurance Requirements

State License Verification

In Connecticut, a licensed concrete contractor must have a valid license to perform work based on the size of the job. Commercial, institutional, and multi-family structures require a major contractor license as stated in Connecticut General Statute 29-276b. Residential projects are registered in the home improvement contractor registry for alteration projects or the New Home Construction Registry for new projects.

Verify your contractor’s license by calling the Connecticut Department of Consumer Protection, providing them with the contractor’s name and license number, and checking the status before entering into any agreement.

Liability and Workers’ Compensation Insurance

Request proof of liability and workers’ compensation insurance. A professional contractor will provide you with certificates of insurance. Liability coverage protects you against lawsuits if an accident occurs while working at your Glenbrook or Springdale property.

Building Permit Requirements (Stamford)

Stamford Building Permit Requirements

The Stamford Building Department’s mission is to protect the health, safety, and welfare of the Stamford community by enforcing the Connecticut Building Code. Contractors should know Stamford’s specific permit requirements and complete the application process.

As part of the application process, ask your contractor if he or she is familiar with applying to BuildingDept@stamfordct.gov and the inspection process. The City requires that a foundation inspection take place after the trenches have been dug and any required forms have been built before placing concrete.

Investigation Fee

Per Stamford Municipal Ordinance Sec. 123-5, when work requiring a building permit has begun prior to the issuance of a permit, an investigation fee can be charged equal to the building permit fee, but no less than $200.00. To avoid this penalty, your contractor should obtain the necessary permits before beginning work.

Code Compliance and Technical Expertise

Connecticut Building Code

You want to hire a contractor who is familiar with the Connecticut Building Code. Specifically for concrete foundations, your contractor should know that all concrete used in precast foundations must have a minimum compressive strength of 5,000 psi at 28 days. If the concrete is exposed to freezing and thawing conditions, it must have air entrainment with a minimum total air content of 5%.

Inspection Requirements

Ask your contractor about their experience with mandatory inspections. Inspections for foundation work must take place after poles or piers have been set or trenches have been dug, with any required forms built and reinforcing steel in place and supported before concrete placement. An inspection also takes place for excavations for thickened slabs intended for bearing wall support.

Preparation and Site Planning

Preparation for your job begins prior to the start of your project. Ask your contractor how he prepares the site for the project. For a concrete slab-on-grade, the area within the foundation walls must be free of all debris, including vegetation, topsoil, and other foreign material. All fill material must be free of vegetation and foreign material and must be compacted to ensure even support of the slab. Fill material cannot exceed 24 inches in height for clean sand or gravel and 8 inches in height for earth.

Weather Conditions

Ask your contractor how he handles weather-related delays. Weather conditions can significantly impact the successful outcome of a concrete project. Specific temperature and moisture levels are needed for the proper curing of concrete. A knowledgeable contractor will plan for the variable weather conditions found in Connecticut.

Materials

Material Testing and Documentation

Effective October 1, 2016, Connecticut requires documentation of concrete suppliers for new residential and commercial buildings due to the pyrrhotite concrete crisis affecting thousands of homes in Connecticut. Ask your contractor who supplies the concrete and what quality controls he uses.

Also, ask your contractor to explain the special requirements for concrete exposed to freezing temperatures. Properties located near Mill River Park or the Mianus River State Park have a higher chance of being exposed to moisture, which would create problems for concrete.

Rebar Requirements

Structural rebar used in the foundation work must comply with one of the following ASTM specifications: A615, A706M, or A996M with a minimum yield strength of 40,000 psi (grade 40). Structural rebar must have a minimum amount of concrete cover of 3/4 inch. Your contractor should include this detail in their proposal.

Transparency and Cost

Detailed Written Estimate

Request that your contractor provide a detailed estimate of the cost for your project. The estimate should list each item separately: materials, labor, permit fees, and other costs. Additional costs may arise for projects located in Stamford’s historic neighborhoods, such as “The Cove,” “The Harbor,” or locations close to the Bartlett Arboretum.

Clear Payment Schedule

Be cautious of contractors who demand large up-front payments. Professional contractors usually do not charge more than a small portion of the contract price until the work is done. Be aware of door-to-door solicitors in your neighborhood, especially those targeting high-end neighborhoods such as Westover or Shippan.

References

Request references from your contractor for jobs recently completed in Stamford. A contractor experienced with the local conditions knows the challenges unique to coastal Connecticut properties, such as soil conditions near Harbor Point, drainage concerns in Turn of River, and other local issues.

Contractor’s Portfolio

Request pictures of your contractor’s completed projects and previous client contact information. It is a good idea to drive by some of the jobs that your contractor claims to have completed in order to verify the validity of their claim.

Warranty

Written Warranty

Ensure that your contractor provides a written warranty covering both the materials and the craftsmanship of the finished product. As previously mentioned, a concrete project is a significant investment, and a legitimate warranty ensures the value of your property, whether you reside in a long-standing neighborhood like Scalzi Park or a new development.

Follow-Up

Post-Job Maintenance Information

A quality contractor will provide you with post-job maintenance information specific to Connecticut’s climate, including salt damage protection for driveways and sidewalks in coastal towns such as Glenbrook.
