Legal Counsel for the Construction Industry

Practice Areas

Construction Litigation

Contractors, subcontractors, construction managers and owners, understand the practical certainty of issues arising during construction. When litigation is necessary, our attorneys have extensive knowledge and experience litigating construction disputes including bond and payment claims, as well as litigation involving changed conditions and claims for delay, inefficiency, disruption and out-of-sequence work.

Construction Defect Claims

Our team has substantial experience representing individual homeowners and homeowner associations in construction defect claims, specifically building envelope failures resulting from defectively installed siding, stucco and exterior insulation and finishing systems (EIFS).

Construction Contracts

Whether you are a contractor, subcontractor or homeowner, you need to know how the terms of a contract you sign affect you. We provide guidance and counsel in the negotiation, drafting, and interpretation of construction contracts and other construction related documents.

Business & Commercial Litigation

When commercial disputes cannot be resolved, we counsel businesses regarding their options and, when necessary, aggressively represent their interests in litigation in all degrees of complexity.

Contractor Termination

If contractors or subcontractors fail to perform in accordance with the terms of their contract, our team will provide guidance in documenting the poor performance and, if necessary, terminating the contract.

Mechanic’s and Construction Liens

Are you a contractor that has not been paid for work performed on a construction project? If so, you may have rights under Pennsylvania’s Mechanic’s Lien Law. We have substantial experience asserting Mechanic’s and Construction Liens on behalf of contractors.

Surety Bonds

In the event of a contractor or subcontractor default on a bonded project, our team will analyze the situation and make the appropriate surety bond claim.


The best defense is a great offense. We arm our clients with employee handbooks and workplace policies that help our clients avoid litigation and many employment pitfalls. We also protect our clients in court, litigating breach of contract, unfair competition and trade secrets disputes, tortious interference, as well as restrictive covenant matters.

MBE/WBE Enterprise Certification

Owners and government entities are increasingly interested in awarding contracts to MBE/WBE contractors. We assist contractors with certification so that they are eligible for this type of work.

Real Estate Transactions

The purchase of real estate, especially a home, is usually the single biggest investment one makes in a lifetime. We represent both sellers and buyers of real estate.

Arbitration and Alternative Dispute Resolution

In the event of a contractual dispute, instead of litigation, many construction contracts require mediation followed by arbitration. Our team handles all aspects of alternative dispute resolution.
