Common questions

Frequently asked

Can you work under a deadline?
Yes. Most of our pre-sale work is deadline-driven. Tell us the closing date.
Will you handle a Mass Smoke Cert / CO inspection requirement?
Yes — we install the right detectors in the right locations for the MA requirements and coordinate with the local fire department inspection.
Do you do Title V septic issues?
No — for Title V, you'll need a licensed septic contractor. We can refer.
Can you work directly with the real estate agent?
With the seller's permission, absolutely — faster for everyone.
