CHIMNEYS: Clean chimneys ONLY IF NECESSARY. Instruct on proper and safe usage. High volume vacuum used to capture all dust. Any repairs needed are explained in detait so home owner can do them. Service usually takes roughly two hours. I like to make sure customer is confident in all aspects of use. DRYER VENTS: Customer, if able, should disconnect dryer from WALL and attach something to capture lint. If drying time is significently recuced the vent is cloged. If drying time is not significently reduced, its time to repair. As this is my full time occupation, Service calls are usually in a day or two. Same day when called early enough. Weekend service is also available.
