Zephyr Thomas is the foremost vinyl siding company Lancaster, PA has to offer. We give you the freedom of choice in siding materials, profiles, and colors. Vinyl siding beats all other types of siding as far as endurance goes. It is impervious to weathering common in other siding types caused by rain, cold, salt, and snow. This siding doesn’t rot or dent and you won’t have to worry about it peeling or getting scratched. Zephyr Thomas uses products by well-known manufacturers such as CertainTeed and Mastic. In terms of overall payback in remodeling projects, re-siding a home is among the top ten. Oftentimes, re-siding with vinyl allows you to get a 100% return on your investment or more! If you need siding in Lancaster, PA, call us!

MainStreet™ siding offers consistent quality, good looks and is the ideal choice for homeowners looking for value with the benefits of a premium panel.
Rigidform™ Technology
RigidForm 160 (rolled-over nail hem) technology stiffens siding for a straighter-on-the-wall appearance and has been tested to withstand wind load pressure up to 160 mph.
DuraLock®
This lock features an oversized rigid tear-drop shape which is substantially larger than many competitors’ locks, providing secure installation. The angular locking leg creates a secure, snap-fit installation, allowing for necessary expansion and contraction.
Available Colors
Monogram is designed to perform in the harshest weather conditions. Many competitive products, even premium thickness panels, do not have the strength in the nail hem area that CertainTeed RigidForm sidings offer, or the added security of a proprietary locking system. Without these design innovations, chances of blow off and weather related problems can be very real possibilities.
Monogram 46 has a long list of features:
Available Colors
No paint. No stain. No hassles. A premium vinyl siding with the classic look of authentic wood siding. Solid and tough. A tornado-tough, double-thick nail hem that keeps siding firmly in position, even during high winds. Patented T3-Lok® panel locking system eases installation and increases strength. Quest. Incomparable beauty. Unmatched performance.

We had two dormers installed in our garage by Zephyr Thomas. Josh Lapham came to our house, took measurements, provided the estimate, and detailed drawings. The project was completed in about a week and the work was done very professionally. We are very happy with the final product and with the entire process.

Our experience with Zephyr Thomas has been nothing less than highly exceptional. From the receptionist to those doing the labor was always extremely personable and professional. The work was of the highest quality in every possible way. Our project consisted of tearing down deck, siding, and fencing and then replacing it all in a very small working area. It was not the easiest job and it was done with utmost perfection. It was an investment well worthwhile and will provide us with much enjoyment and relaxation. We highly recommend Zephyr Thomas. They do the job right. Thanks.
