About BTH Security Doors and Screens
Andrew is the face of BTH Security Doors and Screens, and nearly every review names him specifically — he handles everything from the initial measure-and-quote through to final installation, which means the person who understands your job is the same one who turns up to do it. The business focuses on residential security: new security door installations, window and door screen replacements, sliding door servicing, and door alignment and lock repairs for doors that are sticking, misaligning, or locking unexpectedly. Nick and Deb are also mentioned in reviews, suggesting a small team that can take on multiple jobs without losing the personalised feel customers praise. Andrew is particularly noted for offering multiple product options at quote stage — several reviewers mention receiving quotes across different price points rather than being pushed toward a single solution — and for taking time on-site to get alignment and fit exactly right rather than rushing through an install. Homeowners dealing with aging or malfunctioning security hardware — doors that won't lock, screens that need replacing across a whole house, or sliding doors that have become stiff over years — are exactly who this business is geared toward. Turnaround from quote acceptance to installation regularly comes in ahead of the timeframes quoted, which makes BTH a practical choice for anyone who's already been waiting too long on another supplier.
Best for: whole-house security screen and door replacements, repairs to misaligning or misfiring door locks, and homeowners who want the same person to quote and complete the job.

What types of jobs does BTH Security Doors and Screens typically handle?+
BTH covers both new installations and repairs to existing security hardware. Reviews mention new security door and screen door installations, full window screen replacements across an entire house, sliding door servicing, and repairs to doors that won't lock properly or have come out of alignment. They supply and install the products rather than just fitting customer-supplied materials, and multiple reviewers mention receiving options across different product types at the quote stage.
How does the quoting and installation process work?+
Andrew comes out to measure and quote in person, and in most reviewed cases he also handles the installation himself. Customers consistently note that the quote process is transparent and that multiple product options are offered rather than a single price. Several reviewers mention the installation was completed earlier than the timeframe given at the time of the quote, suggesting lead times quoted tend to be conservative.
What do customers say about BTH's pricing?+
Pricing is described across multiple reviews as competitive and reasonable relative to the quality of materials used. A few customers specifically mention having compared BTH against other companies and finding the value strong. There is one review raising a concern about a quoting miscommunication where a customer felt the quantity per item wasn't clearly spelled out — worth confirming the exact scope and unit pricing in writing when accepting a quote, particularly for jobs involving multiple doors of the same type.
Who will actually turn up to do the work?+
In the large majority of reviews, Andrew is named as the person who both quoted and carried out the installation. Nick and Deb are mentioned in at least one review, suggesting BTH operates as a small team rather than a solo operator, which provides some capacity for larger or concurrent jobs. The personalised, consistent contact from one person is something customers specifically praise — you're unlikely to deal with a rotating roster of subcontractors.
Is BTH suitable for repairs to older or malfunctioning doors, or just new installs?+
Yes — repairs to existing doors are a notable part of what BTH does, based on the reviews. Customers mention having stiff and creaking screen doors fixed, sliding security doors that were locking by themselves corrected, and front security doors brought back into alignment so they lock properly. If you have an aging door that's become difficult to use rather than needing a full replacement, that's a job BTH has handled for other customers in similar situations.
